-## TOML parser and encoder for Go with reflection
-
-TOML stands for Tom's Obvious, Minimal Language. This Go package provides a
-reflection interface similar to Go's standard library `json` and `xml`
-packages. This package also supports the `encoding.TextUnmarshaler` and
-`encoding.TextMarshaler` interfaces so that you can define custom data
-representations. (There is an example of this below.)
-
-Spec: https://github.com/toml-lang/toml
-
-Compatible with TOML version
-[v0.4.0](https://github.com/toml-lang/toml/blob/master/versions/en/toml-v0.4.0.md)
-
-Documentation: https://godoc.org/github.com/BurntSushi/toml
-
-Installation:
-
-```bash
-go get github.com/BurntSushi/toml
-```
-
-Try the toml validator:
-
-```bash
-go get github.com/BurntSushi/toml/cmd/tomlv
-tomlv some-toml-file.toml
-```
-
-[![Build Status](https://travis-ci.org/BurntSushi/toml.svg?branch=master)](https://travis-ci.org/BurntSushi/toml) [![GoDoc](https://godoc.org/github.com/BurntSushi/toml?status.svg)](https://godoc.org/github.com/BurntSushi/toml)
-
-### Testing
-
-This package passes all tests in
-[toml-test](https://github.com/BurntSushi/toml-test) for both the decoder
-and the encoder.
-
-### Examples
-
-This package works similarly to how the Go standard library handles `XML`
-and `JSON`. Namely, data is loaded into Go values via reflection.
-
-For the simplest example, consider some TOML file as just a list of keys
-and values:
-
-```toml
-Age = 25
-Cats = [ "Cauchy", "Plato" ]
-Pi = 3.14
-Perfection = [ 6, 28, 496, 8128 ]
-DOB = 1987-07-05T05:45:00Z
-```
-
-Which could be defined in Go as:
-
-```go
-type Config struct {
-  Age int
-  Cats []string
-  Pi float64
-  Perfection []int
-  DOB time.Time // requires `import time`
-}
-```
-
-And then decoded with:
-
-```go
-var conf Config
-if _, err := toml.Decode(tomlData, &conf); err != nil {
-  // handle error
-}
-```
-
-You can also use struct tags if your struct field name doesn't map to a TOML
-key value directly:
-
-```toml
-some_key_NAME = "wat"
-```
-
-```go
-type TOML struct {
-  ObscureKey string `toml:"some_key_NAME"`
-}
-```
-
-### Using the `encoding.TextUnmarshaler` interface
-
-Here's an example that automatically parses duration strings into
-`time.Duration` values:
-
-```toml
-[[song]]
-name = "Thunder Road"
-duration = "4m49s"
-
-[[song]]
-name = "Stairway to Heaven"
-duration = "8m03s"
-```
-
-Which can be decoded with:
-
-```go
-type song struct {
-  Name     string
-  Duration duration
-}
-type songs struct {
-  Song []song
-}
-var favorites songs
-if _, err := toml.Decode(blob, &favorites); err != nil {
-  log.Fatal(err)
-}
-
-for _, s := range favorites.Song {
-  fmt.Printf("%s (%s)\n", s.Name, s.Duration)
-}
-```
-
-And you'll also need a `duration` type that satisfies the
-`encoding.TextUnmarshaler` interface:
-
-```go
-type duration struct {
-	time.Duration
-}
-
-func (d *duration) UnmarshalText(text []byte) error {
-	var err error
-	d.Duration, err = time.ParseDuration(string(text))
-	return err
-}
-```
-
-### More complex usage
-
-Here's an example of how to load the example from the official spec page:
-
-```toml
-# This is a TOML document. Boom.
-
-title = "TOML Example"
-
-[owner]
-name = "Tom Preston-Werner"
-organization = "GitHub"
-bio = "GitHub Cofounder & CEO\nLikes tater tots and beer."
-dob = 1979-05-27T07:32:00Z # First class dates? Why not?
-
-[database]
-server = "192.168.1.1"
-ports = [ 8001, 8001, 8002 ]
-connection_max = 5000
-enabled = true
-
-[servers]
-
-  # You can indent as you please. Tabs or spaces. TOML don't care.
-  [servers.alpha]
-  ip = "10.0.0.1"
-  dc = "eqdc10"
-
-  [servers.beta]
-  ip = "10.0.0.2"
-  dc = "eqdc10"
-
-[clients]
-data = [ ["gamma", "delta"], [1, 2] ] # just an update to make sure parsers support it
-
-# Line breaks are OK when inside arrays
-hosts = [
-  "alpha",
-  "omega"
-]
-```
-
-And the corresponding Go types are:
-
-```go
-type tomlConfig struct {
-	Title string
-	Owner ownerInfo
-	DB database `toml:"database"`
-	Servers map[string]server
-	Clients clients
-}
-
-type ownerInfo struct {
-	Name string
-	Org string `toml:"organization"`
-	Bio string
-	DOB time.Time
-}
-
-type database struct {
-	Server string
-	Ports []int
-	ConnMax int `toml:"connection_max"`
-	Enabled bool
-}
-
-type server struct {
-	IP string
-	DC string
-}
-
-type clients struct {
-	Data [][]interface{}
-	Hosts []string
-}
-```
-
-Note that a case insensitive match will be tried if an exact match can't be
-found.
-
-A working example of the above can be found in `_examples/example.{go,toml}`.

-//
-// All other TOML types (float, string, int, bool and array) correspond

-// (floats, strings, integers, booleans and datetimes) will be converted to
-// a byte string and given to the value's UnmarshalText method. See the
-// Unmarshaler example for a demonstration with time duration strings.
-//
-// Key mapping
-//
-// TOML keys can map to either keys in a Go map or field names in a Go
-// struct. The special `toml` struct tag may be used to map TOML keys to
-// struct fields that don't match the key name exactly. (See the example.)
-// A case insensitive match to struct names will be tried if an exact match
-// can't be found.
-//

-Package toml provides facilities for decoding and encoding TOML configuration

-MetaData type.
-
-The specification implemented: https://github.com/toml-lang/toml
-
-The sub-command github.com/BurntSushi/toml/cmd/tomlv can be used to verify
-whether a file is a valid TOML document. It can also be used to print the
-type of each key in a TOML document.
-
-Testing
-
-There are two important types of tests used for this package. The first is
-contained inside '*_test.go' files and uses the standard Go unit testing
-framework. These tests are primarily devoted to holistically testing the
-decoder and encoder.
-
-The second type of testing is used to verify the implementation's adherence
-to the TOML specification. These tests have been factored into their own
-project: https://github.com/BurntSushi/toml-test
-
-The reason the tests are in a separate project is so that they can be used by
-any implementation of TOML. Namely, it is language agnostic.

-
-      You may add Your own copyright statement to Your modifications and

-      reproduction, and distribution of the Work otherwise complies with
-      the conditions stated in this License.
-
-   5. Submission of Contributions. Unless You explicitly state otherwise,
-      any Contribution intentionally submitted for inclusion in the Work
-      by You to the Licensor shall be under the terms and conditions of
-      this License, without any additional terms or conditions.
-      Notwithstanding the above, nothing herein shall supersede or modify
-      the terms of any separate license agreement you may have executed
-      with Licensor regarding such Contributions.
-
-   6. Trademarks. This License does not grant permission to use the trade
-      names, trademarks, service marks, or product names of the Licensor,
-      except as required for reasonable and customary use in describing the
-      origin of the Work and reproducing the content of the NOTICE file.

-   7. Disclaimer of Warranty. Unless required by applicable law or
-      agreed to in writing, Licensor provides the Work (and each
-      Contributor provides its Contributions) on an "AS IS" BASIS,
-      WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
-      implied, including, without limitation, any warranties or conditions

-      PARTICULAR PURPOSE. You are solely responsible for determining the
-      appropriateness of using or redistributing the Work and assume any
-      risks associated with Your exercise of permissions under this License.
-
-   8. Limitation of Liability. In no event and under no legal theory,
-      whether in tort (including negligence), contract, or otherwise,
-      unless required by applicable law (such as deliberate and grossly
-      negligent acts) or agreed to in writing, shall any Contributor be
-      liable to You for damages, including any direct, indirect, special,
-      incidental, or consequential damages of any character arising as a
-      result of this License or out of the use or inability to use the
-      Work (including but not limited to damages for loss of goodwill,
-      work stoppage, computer failure or malfunction, or any and all
-      other commercial damages or losses), even if such Contributor
-      has been advised of the possibility of such damages.
-
-   9. Accepting Warranty or Additional Liability. While redistributing
-      the Work or Derivative Works thereof, You may choose to offer,
-      and charge a fee for, acceptance of support, warranty, indemnity,
-      or other liability obligations and/or rights consistent with this
-      License. However, in accepting such obligations, You may act only
-      on Your own behalf and on Your sole responsibility, not on behalf
-      of any other Contributor, and only if You agree to indemnify,
-      defend, and hold each Contributor harmless for any liability
-      incurred by, or claims asserted against, such Contributor by reason
-      of your accepting any such warranty or additional liability.

-===========
-[![Stability: Maintenance](https://masterminds.github.io/stability/maintenance.svg)](https://masterminds.github.io/stability/maintenance.html)
-[![GoDoc](https://godoc.org/github.com/Masterminds/goutils?status.png)](https://godoc.org/github.com/Masterminds/goutils) [![Build Status](https://travis-ci.org/Masterminds/goutils.svg?branch=master)](https://travis-ci.org/Masterminds/goutils) [![Build status](https://ci.appveyor.com/api/projects/status/sc2b1ew0m7f0aiju?svg=true)](https://ci.appveyor.com/project/mattfarina/goutils)
-
-
-GoUtils provides users with utility functions to manipulate strings in various ways. It is a Go implementation of some
-string manipulation libraries of Java Apache Commons. GoUtils includes the following Java Apache Commons classes:
-* WordUtils    
-* RandomStringUtils  
-* StringUtils (partial implementation)
-
-## Installation
-If you have Go set up on your system, from the GOPATH directory within the command line/terminal, enter this:
-
-	go get github.com/Masterminds/goutils
-
-If you do not have Go set up on your system, please follow the [Go installation directions from the documenation](http://golang.org/doc/install), and then follow the instructions above to install GoUtils.
-
-
-## Documentation
-GoUtils doc is available here: [![GoDoc](https://godoc.org/github.com/Masterminds/goutils?status.png)](https://godoc.org/github.com/Masterminds/goutils)
-
-
-## Usage
-The code snippets below show examples of how to use GoUtils. Some functions return errors while others do not. The first instance below, which does not return an error, is the `Initials` function (located within the `wordutils.go` file).
-
-    package main
-
-    import (
-        "fmt"
-    	"github.com/Masterminds/goutils"
-    )
-
-    func main() {
-
-    	// EXAMPLE 1: A goutils function which returns no errors
-        fmt.Println (goutils.Initials("John Doe Foo")) // Prints out "JDF"
-
-    }
-Some functions return errors mainly due to illegal arguements used as parameters. The code example below illustrates how to deal with function that returns an error. In this instance, the function is the `Random` function (located within the `randomstringutils.go` file).
-
-    package main
-
-    import (
-        "fmt"
-        "github.com/Masterminds/goutils"
-    )
-
-    func main() {
-
-        // EXAMPLE 2: A goutils function which returns an error
-        rand1, err1 := goutils.Random (-1, 0, 0, true, true)  
-
-        if err1 != nil {
-			fmt.Println(err1) // Prints out error message because -1 was entered as the first parameter in goutils.Random(...)
-		} else {
-			fmt.Println(rand1)
-		}
-
-    }
-

-# SemVer
-
-The `semver` package provides the ability to work with [Semantic Versions](http://semver.org) in Go. Specifically it provides the ability to:
-
-* Parse semantic versions
-* Sort semantic versions
-* Check if a semantic version fits within a set of constraints
-* Optionally work with a `v` prefix
-
-[![Stability:
-Active](https://masterminds.github.io/stability/active.svg)](https://masterminds.github.io/stability/active.html)
-[![Build Status](https://travis-ci.org/Masterminds/semver.svg)](https://travis-ci.org/Masterminds/semver) [![Build status](https://ci.appveyor.com/api/projects/status/jfk66lib7hb985k8/branch/master?svg=true&passingText=windows%20build%20passing&failingText=windows%20build%20failing)](https://ci.appveyor.com/project/mattfarina/semver/branch/master) [![GoDoc](https://godoc.org/github.com/Masterminds/semver?status.svg)](https://godoc.org/github.com/Masterminds/semver) [![Go Report Card](https://goreportcard.com/badge/github.com/Masterminds/semver)](https://goreportcard.com/report/github.com/Masterminds/semver)
-
-If you are looking for a command line tool for version comparisons please see
-[vert](https://github.com/Masterminds/vert) which uses this library.
-
-## Parsing Semantic Versions
-
-To parse a semantic version use the `NewVersion` function. For example,
-
-```go
-    v, err := semver.NewVersion("1.2.3-beta.1+build345")
-```
-
-If there is an error the version wasn't parseable. The version object has methods
-to get the parts of the version, compare it to other versions, convert the
-version back into a string, and get the original string. For more details
-please see the [documentation](https://godoc.org/github.com/Masterminds/semver).
-
-## Sorting Semantic Versions
-
-A set of versions can be sorted using the [`sort`](https://golang.org/pkg/sort/)
-package from the standard library. For example,
-
-```go
-    raw := []string{"1.2.3", "1.0", "1.3", "2", "0.4.2",}
-    vs := make([]*semver.Version, len(raw))
-	for i, r := range raw {
-		v, err := semver.NewVersion(r)
-		if err != nil {
-			t.Errorf("Error parsing version: %s", err)
-		}
-
-		vs[i] = v
-	}
-
-	sort.Sort(semver.Collection(vs))
-```
-
-## Checking Version Constraints
-
-Checking a version against version constraints is one of the most featureful
-parts of the package.
-
-```go
-    c, err := semver.NewConstraint(">= 1.2.3")
-    if err != nil {
-        // Handle constraint not being parseable.
-    }
-
-    v, _ := semver.NewVersion("1.3")
-    if err != nil {
-        // Handle version not being parseable.
-    }
-    // Check if the version meets the constraints. The a variable will be true.
-    a := c.Check(v)
-```
-
-## Basic Comparisons
-
-There are two elements to the comparisons. First, a comparison string is a list
-of comma separated and comparisons. These are then separated by || separated or
-comparisons. For example, `">= 1.2, < 3.0.0 || >= 4.2.3"` is looking for a
-comparison that's greater than or equal to 1.2 and less than 3.0.0 or is
-greater than or equal to 4.2.3.
-
-The basic comparisons are:
-
-* `=`: equal (aliased to no operator)
-* `!=`: not equal
-* `>`: greater than
-* `<`: less than
-* `>=`: greater than or equal to
-* `<=`: less than or equal to
-
-## Working With Pre-release Versions
-
-Pre-releases, for those not familiar with them, are used for software releases
-prior to stable or generally available releases. Examples of pre-releases include
-development, alpha, beta, and release candidate releases. A pre-release may be
-a version such as `1.2.3-beta.1` while the stable release would be `1.2.3`. In the
-order of precidence, pre-releases come before their associated releases. In this
-example `1.2.3-beta.1 < 1.2.3`.
-
-According to the Semantic Version specification pre-releases may not be
-API compliant with their release counterpart. It says,
-
-> A pre-release version indicates that the version is unstable and might not satisfy the intended compatibility requirements as denoted by its associated normal version.
-
-SemVer comparisons without a pre-release comparator will skip pre-release versions.
-For example, `>=1.2.3` will skip pre-releases when looking at a list of releases
-while `>=1.2.3-0` will evaluate and find pre-releases.
-
-The reason for the `0` as a pre-release version in the example comparison is
-because pre-releases can only contain ASCII alphanumerics and hyphens (along with
-`.` separators), per the spec. Sorting happens in ASCII sort order, again per the spec. The lowest character is a `0` in ASCII sort order (see an [ASCII Table](http://www.asciitable.com/))
-
-Understanding ASCII sort ordering is important because A-Z comes before a-z. That
-means `>=1.2.3-BETA` will return `1.2.3-alpha`. What you might expect from case
-sensitivity doesn't apply here. This is due to ASCII sort ordering which is what
-the spec specifies.
-
-## Hyphen Range Comparisons
-
-There are multiple methods to handle ranges and the first is hyphens ranges.
-These look like:
-
-* `1.2 - 1.4.5` which is equivalent to `>= 1.2, <= 1.4.5`
-* `2.3.4 - 4.5` which is equivalent to `>= 2.3.4, <= 4.5`
-
-## Wildcards In Comparisons
-
-The `x`, `X`, and `*` characters can be used as a wildcard character. This works
-for all comparison operators. When used on the `=` operator it falls
-back to the pack level comparison (see tilde below). For example,
-
-* `1.2.x` is equivalent to `>= 1.2.0, < 1.3.0`
-* `>= 1.2.x` is equivalent to `>= 1.2.0`
-* `<= 2.x` is equivalent to `< 3`
-* `*` is equivalent to `>= 0.0.0`
-
-## Tilde Range Comparisons (Patch)
-
-The tilde (`~`) comparison operator is for patch level ranges when a minor
-version is specified and major level changes when the minor number is missing.
-For example,
-
-* `~1.2.3` is equivalent to `>= 1.2.3, < 1.3.0`
-* `~1` is equivalent to `>= 1, < 2`
-* `~2.3` is equivalent to `>= 2.3, < 2.4`
-* `~1.2.x` is equivalent to `>= 1.2.0, < 1.3.0`
-* `~1.x` is equivalent to `>= 1, < 2`
-
-## Caret Range Comparisons (Major)
-
-The caret (`^`) comparison operator is for major level changes. This is useful
-when comparisons of API versions as a major change is API breaking. For example,
-
-* `^1.2.3` is equivalent to `>= 1.2.3, < 2.0.0`
-* `^0.0.1` is equivalent to `>= 0.0.1, < 1.0.0`
-* `^1.2.x` is equivalent to `>= 1.2.0, < 2.0.0`
-* `^2.3` is equivalent to `>= 2.3, < 3`
-* `^2.x` is equivalent to `>= 2.0.0, < 3`
-
-# Validation
-
-In addition to testing a version against a constraint, a version can be validated
-against a constraint. When validation fails a slice of errors containing why a
-version didn't meet the constraint is returned. For example,
-
-```go
-    c, err := semver.NewConstraint("<= 1.2.3, >= 1.4")
-    if err != nil {
-        // Handle constraint not being parseable.
-    }
-
-    v, _ := semver.NewVersion("1.3")
-    if err != nil {
-        // Handle version not being parseable.
-    }
-
-    // Validate a version against a constraint.
-    a, msgs := c.Validate(v)
-    // a is false
-    for _, m := range msgs {
-        fmt.Println(m)
-
-        // Loops over the errors which would read
-        // "1.3 is greater than 1.2.3"
-        // "1.3 is less than 1.4"
-    }
-```

-/*
-Package semver provides the ability to work with Semantic Versions (http://semver.org) in Go.
-
-Specifically it provides the ability to:
-
-    * Parse semantic versions
-    * Sort semantic versions
-    * Check if a semantic version fits within a set of constraints
-    * Optionally work with a `v` prefix
-
-Parsing Semantic Versions
-
-To parse a semantic version use the `NewVersion` function. For example,
-
-    v, err := semver.NewVersion("1.2.3-beta.1+build345")
-
-If there is an error the version wasn't parseable. The version object has methods
-to get the parts of the version, compare it to other versions, convert the
-version back into a string, and get the original string. For more details
-please see the documentation at https://godoc.org/github.com/Masterminds/semver.
-
-Sorting Semantic Versions
-
-A set of versions can be sorted using the `sort` package from the standard library.
-For example,
-
-    raw := []string{"1.2.3", "1.0", "1.3", "2", "0.4.2",}
-    vs := make([]*semver.Version, len(raw))
-	for i, r := range raw {
-		v, err := semver.NewVersion(r)
-		if err != nil {
-			t.Errorf("Error parsing version: %s", err)
-		}
-
-		vs[i] = v
-	}
-
-	sort.Sort(semver.Collection(vs))
-
-Checking Version Constraints
-
-Checking a version against version constraints is one of the most featureful
-parts of the package.
-
-    c, err := semver.NewConstraint(">= 1.2.3")
-    if err != nil {
-        // Handle constraint not being parseable.
-    }
-
-    v, err := semver.NewVersion("1.3")
-    if err != nil {
-        // Handle version not being parseable.
-    }
-    // Check if the version meets the constraints. The a variable will be true.
-    a := c.Check(v)
-
-Basic Comparisons
-
-There are two elements to the comparisons. First, a comparison string is a list
-of comma separated and comparisons. These are then separated by || separated or
-comparisons. For example, `">= 1.2, < 3.0.0 || >= 4.2.3"` is looking for a
-comparison that's greater than or equal to 1.2 and less than 3.0.0 or is
-greater than or equal to 4.2.3.
-
-The basic comparisons are:
-
-    * `=`: equal (aliased to no operator)
-    * `!=`: not equal
-    * `>`: greater than
-    * `<`: less than
-    * `>=`: greater than or equal to
-    * `<=`: less than or equal to
-
-Hyphen Range Comparisons
-
-There are multiple methods to handle ranges and the first is hyphens ranges.
-These look like:
-
-    * `1.2 - 1.4.5` which is equivalent to `>= 1.2, <= 1.4.5`
-    * `2.3.4 - 4.5` which is equivalent to `>= 2.3.4, <= 4.5`
-
-Wildcards In Comparisons
-
-The `x`, `X`, and `*` characters can be used as a wildcard character. This works
-for all comparison operators. When used on the `=` operator it falls
-back to the pack level comparison (see tilde below). For example,
-
-    * `1.2.x` is equivalent to `>= 1.2.0, < 1.3.0`
-    * `>= 1.2.x` is equivalent to `>= 1.2.0`
-    * `<= 2.x` is equivalent to `<= 3`
-    * `*` is equivalent to `>= 0.0.0`
-
-Tilde Range Comparisons (Patch)
-
-The tilde (`~`) comparison operator is for patch level ranges when a minor
-version is specified and major level changes when the minor number is missing.
-For example,
-
-    * `~1.2.3` is equivalent to `>= 1.2.3, < 1.3.0`
-    * `~1` is equivalent to `>= 1, < 2`
-    * `~2.3` is equivalent to `>= 2.3, < 2.4`
-    * `~1.2.x` is equivalent to `>= 1.2.0, < 1.3.0`
-    * `~1.x` is equivalent to `>= 1, < 2`
-
-Caret Range Comparisons (Major)
-
-The caret (`^`) comparison operator is for major level changes. This is useful
-when comparisons of API versions as a major change is API breaking. For example,
-
-    * `^1.2.3` is equivalent to `>= 1.2.3, < 2.0.0`
-    * `^1.2.x` is equivalent to `>= 1.2.0, < 2.0.0`
-    * `^2.3` is equivalent to `>= 2.3, < 3`
-    * `^2.x` is equivalent to `>= 2.0.0, < 3`

-
-### Fixed
-
-## Release 2.19.0 (2019-03-02)
-
-IMPORTANT: This release reverts a change from 2.18.0
-
-In the previous release (2.18), we prematurely merged a partial change to the crypto functions that led to creating two sets of crypto functions (I blame @technosophos -- since that's me). This release rolls back that change, and does what was originally intended: It alters the existing crypto functions to use secure random.
-
-We debated whether this classifies as a change worthy of major revision, but given the proximity to the last release, we have decided that treating 2.18 as a faulty release is the correct course of action. We apologize for any inconvenience.
-

-# Sprig: Template functions for Go templates
-[![Stability: Sustained](https://masterminds.github.io/stability/sustained.svg)](https://masterminds.github.io/stability/sustained.html)
-[![Build Status](https://travis-ci.org/Masterminds/sprig.svg?branch=master)](https://travis-ci.org/Masterminds/sprig)
-
-The Go language comes with a [built-in template
-language](http://golang.org/pkg/text/template/), but not
-very many template functions. Sprig is a library that provides more than 100 commonly
-used template functions.
-
-It is inspired by the template functions found in
-[Twig](http://twig.sensiolabs.org/documentation) and in various
-JavaScript libraries, such as [underscore.js](http://underscorejs.org/).
-
-## Usage
-
-**Template developers**: Please use Sprig's [function documentation](http://masterminds.github.io/sprig/) for
-detailed instructions and code snippets for the >100 template functions available.
-
-**Go developers**: If you'd like to include Sprig as a library in your program,
-our API documentation is available [at GoDoc.org](http://godoc.org/github.com/Masterminds/sprig).
-
-For standard usage, read on.
-
-### Load the Sprig library
-
-To load the Sprig `FuncMap`:
-
-```go
-
-import (
-  "github.com/Masterminds/sprig"
-  "html/template"
-)
-
-// This example illustrates that the FuncMap *must* be set before the
-// templates themselves are loaded.
-tpl := template.Must(
-  template.New("base").Funcs(sprig.FuncMap()).ParseGlob("*.html")
-)
-
-
-```
-
-### Calling the functions inside of templates
-
-By convention, all functions are lowercase. This seems to follow the Go
-idiom for template functions (as opposed to template methods, which are
-TitleCase). For example, this:
-
-```
-{{ "hello!" | upper | repeat 5 }}
-```
-
-produces this:
-
-```
-HELLO!HELLO!HELLO!HELLO!HELLO!
-```
-
-## Principles Driving Our Function Selection
-
-We followed these principles to decide which functions to add and how to implement them:
-
-- Use template functions to build layout. The following
-  types of operations are within the domain of template functions:
-  - Formatting
-  - Layout
-  - Simple type conversions
-  - Utilities that assist in handling common formatting and layout needs (e.g. arithmetic)
-- Template functions should not return errors unless there is no way to print
-  a sensible value. For example, converting a string to an integer should not
-  produce an error if conversion fails. Instead, it should display a default
-  value.
-- Simple math is necessary for grid layouts, pagers, and so on. Complex math
-  (anything other than arithmetic) should be done outside of templates.
-- Template functions only deal with the data passed into them. They never retrieve
-  data from a source.
-- Finally, do not override core Go template functions.
