-## Functions
-
-### Date Functions
-
-- date: Format a date, where a date is an integer type or a time.Time type, and
-  format is a time.Format formatting string.
-- dateModify: Given a date, modify it with a duration: `date_modify "-1.5h" now`. If the duration doesn't
-parse, it returns the time unaltered. See `time.ParseDuration` for info on duration strings.
-- now: Current time.Time, for feeding into date-related functions.
-- htmlDate: Format a date for use in the value field of an HTML "date" form element.
-- dateInZone: Like date, but takes three arguments: format, timestamp,
-  timezone.
-- htmlDateInZone: Like htmlDate, but takes two arguments: timestamp,
-  timezone.
-
-### String Functions
-
-- trim: strings.TrimSpace
-- trimAll: strings.Trim, but with the argument order reversed `trimAll "$" "$5.00"` or `"$5.00 | trimAll "$"`
-- trimSuffix: strings.TrimSuffix, but with the argument order reversed `trimSuffix "-" "5-"`
-- trimPrefix: strings.TrimPrefix, but with the argument order reversed `trimPrefix "$" "$5"`
-- upper: strings.ToUpper
-- lower: strings.ToLower
-- title: strings.Title
-- repeat: strings.Repeat, but with the arguments switched: `repeat count str`. (This simplifies common pipelines)
-- substr: Given string, start, and length, return a substr.
-- nospace: Remove all spaces from a string. `h e l l o` becomes
-  `hello`.
-- abbrev: Truncate a string with ellipses
-- trunc: Truncate a string (no suffix). `trunc 5 "Hello World"` yields "hello".
-- abbrevboth: Truncate both sides of a string with ellipses
-- untitle: Remove title case
-- intials: Given multiple words, return the first letter of each
-  word
-- randAlphaNum: Generate a random alpha-numeric string
-- randAlpha: Generate a random alphabetic string
-- randAscii: Generate a random ASCII string, including symbols
-- randNumeric: Generate a random numeric string
-- wrap: Wrap text at the given column count
-- wrapWith: Wrap text at the given column count, and with the given
-  string for a line terminator: `wrap 50 "\n\t" $string`
-- contains: strings.Contains, but with the arguments switched: `contains "cat" "uncatch"`. (This simplifies common pipelines)
-- hasPrefix: strings.hasPrefix, but with the arguments switched: `hasPrefix "cat" "catch"`.
-- hasSuffix: strings.hasSuffix, but with the arguments switched: `hasSuffix "cat" "ducat"`.
-- quote: Wrap strings in double quotes. `quote "a" "b"` returns `"a"
-  "b"`
-- squote: Wrap strings in single quotes.
-- cat: Concatenate strings, separating them by spaces. `cat $a $b $c`.
-- indent: Indent a string using space characters. `indent 4 "foo\nbar"` produces "    foo\n    bar"
-- replace: Replace an old with a new in a string: `$name | replace " " "-"`
-- plural: Choose singular or plural based on length: `len $fish | plural
-  "one anchovy" "many anchovies"`
-- uuidv4: Generate a UUID v4 string
-- sha256sum: Generate a hex encoded sha256 hash of the input
-- toString: Convert something to a string
-
-### String Slice Functions:
-
-- join: strings.Join, but as `join SEP SLICE`
-- split: strings.Split, but as `split SEP STRING`. The results are returned
-  as a map with the indexes set to _N, where N is an integer starting from 0.
-  Use it like this: `{{$v := "foo/bar/baz" | split "/"}}{{$v._0}}` (Prints `foo`)
-- splitList: strings.Split, but as `split SEP STRING`. The results are returned
-  as an array.
-- toStrings: convert a list to a list of strings. 'list 1 2 3 | toStrings' produces '["1" "2" "3"]'
-- sortAlpha: sort a list lexicographically.
-
-### Integer Slice Functions:
-
-- until: Given an integer, returns a slice of counting integers from 0 to one
-	  less than the given integer: `range $i, $e := until 5`
-- untilStep: Given start, stop, and step, return an integer slice starting at
-	  'start', stopping at `stop`, and incrementing by 'step'. This is the same
-	  as Python's long-form of 'range'.
-
-### Conversions:
-
-- atoi: Convert a string to an integer. 0 if the integer could not be parsed.
-- int: Convert a string or numeric to an int
-- int64: Convert a string or numeric to an int64
-- float64: Convert a string or numeric to a float64
-
-### Defaults:
-
-- default: Give a default value. Used like this: {{trim "   "| default "empty"}}.
-  Since trim produces an empty string, the default value is returned. For
-  things with a length (strings, slices, maps), len(0) will trigger the default.
-  For numbers, the value 0 will trigger the default. For booleans, false will
-  trigger the default. For structs, the default is never returned (there is
-  no clear empty condition). For everything else, nil value triggers a default.
-- empty: Returns true if the given value is the zero value for that
-  type. Structs are always non-empty.
-- coalesce: Given a list of items, return the first non-empty one.
-  This follows the same rules as 'empty'. `{{ coalesce .someVal 0 "hello" }}`
-  will return `.someVal` if set, or else return "hello". The 0 is skipped
-  because it is an empty value.
-- compact: Return a copy of a list with all of the empty values removed.
-  `list 0 1 2 "" | compact` will return `[1 2]`
-
-### OS:
-
-- env: Read an environment variable.
-- expandenv: Expand all environment variables in a string.
-
-### File Paths:
-- base: Return the last element of a path. https://golang.org/pkg/path#Base
-- dir: Remove the last element of a path. https://golang.org/pkg/path#Dir
-- clean: Clean a path to the shortest equivalent name.  (e.g. remove "foo/.."
-  from "foo/../bar.html") https://golang.org/pkg/path#Clean
-- ext: Get the extension for a file path: https://golang.org/pkg/path#Ext
-- isAbs: Returns true if a path is absolute: https://golang.org/pkg/path#IsAbs
-
-### Encoding:
-
-- b32enc: Encode a string into a Base32 string
-- b32dec: Decode a string from a Base32 string
-- b64enc: Encode a string into a Base64 string
-- b64dec: Decode a string from a Base64 string
-
-### Data Structures:
-
-- tuple: Takes an arbitrary list of items and returns a slice of items. Its
-  tuple-ish properties are mainly gained through the template idiom, and not
-  through an API provided here. WARNING: The implementation of tuple will
-  change in the future.
-- list: An arbitrary ordered list of items. (This is prefered over tuple.)
-- dict: Takes a list of name/values and returns a map[string]interface{}.
-  The first parameter is converted to a string and stored as a key, the
-  second parameter is treated as the value. And so on, with odds as keys and
-  evens as values. If the function call ends with an odd, the last key will
-  be assigned the empty string. Non-string keys are converted to strings as
-  follows: []byte are converted, fmt.Stringers will have String() called.
-  errors will have Error() called. All others will be passed through
-  fmt.Sprtinf("%v"). _dicts are unordered_.
-
-List:
-
-```
-{{$t := list 1 "a" "foo"}}
-{{index $t 2}}{{index $t 0 }}{{index $t 1}}
-{{/* Prints foo1a *}}
-```
-
-Dict:
-```
-{{ $t := map "key1" "value1" "key2" "value2" }}
-{{ $t.key2 }}
-{{ /* Prints value2 *}}
-```
-
-
-### Lists Functions:
-
-These are used to manipulate lists: `{{ list 1 2 3 | reverse | first }}`
-
-- first: Get the first item in a 'list'. 'list 1 2 3 | first' prints '1'
-- last: Get the last item in a 'list': 'list 1 2 3 | last ' prints '3'
-- rest: Get all but the first item in a list: 'list 1 2 3 | rest' returns '[2 3]'
-- initial: Get all but the last item in a list: 'list 1 2 3 | initial' returns '[1 2]'
-- append: Add an item to the end of a list: 'append $list 4' adds '4' to the end of '$list'
-- prepend: Add an item to the beginning of a list: 'prepend $list 4' puts 4 at the beginning of the list.
-- reverse: Reverse the items in a list.
-- uniq: Remove duplicates from a list.
-- without: Return a list with the given values removed: 'without (list 1 2 3) 1' would return '[2 3]'
-- has: Return 'tru' if the item is found in the list: 'has "foo" $list' will return 'true' if the list contains "foo"
-
-### Dict Functions:
-
-These are used to manipulate dicts.
-
-- set: Takes a dict, a key, and a value, and sets that key/value pair in
-  the dict. `set $dict $key $value`. For convenience, it returns the dict,
-  even though the dict was modified in place.
-- unset: Takes a dict and a key, and deletes that key/value pair from the
-  dict. `unset $dict $key`. This returns the dict for convenience.
-- hasKey: Takes a dict and a key, and returns boolean true if the key is in
-  the dict.
-- pluck: Given a key and one or more maps, get all of the values for that key.
-- keys: Get an array of all of the keys in a dict. Order is not guaranteed.
-- pick: Select just the given keys out of the dict, and return a new dict.
-- omit: Return a dict without the given keys.
-
-### Reflection:
-
-- typeOf: Takes an interface and returns a string representation of the type.
-  For pointers, this will return a type prefixed with an asterisk(`*`). So
-  a pointer to type `Foo` will be `*Foo`.
-- typeIs: Compares an interface with a string name, and returns true if they match.
-  Note that a pointer will not match a reference. For example `*Foo` will not
-  match `Foo`.
-- typeIsLike: returns true if the interface is of the given type, or
-  is a pointer to the given type.
-- kindOf: Takes an interface and returns a string representation of its kind.
-- kindIs: Returns true if the given string matches the kind of the given interface.
-
-	Note: None of these can test whether or not something implements a given
-	interface, since doing so would require compiling the interface in ahead of
-	time.
-
-
-### Math Functions:
-
-Integer functions will convert integers of any width to `int64`. If a
-string is passed in, functions will attempt to conver with
-`strconv.ParseInt(s, 1064)`. If this fails, the value will be treated as 0.
-
-- add1: Increment an integer by 1
-- add: Sum integers. `add 1 2 3` renders `6`
-- sub: Subtract the second integer from the first
-- div: Divide the first integer by the second
-- mod: Module of first integer divided by second
-- mul: Multiply integers integers
-- max (biggest): Return the biggest of a series of integers. `max 1 2 3`
-  returns `3`.
-- min: Return the smallest of a series of integers. `min 1 2 3` returns
-  `1`.
-
-### Cryptographic Functions:
-
-- derivePassword: Derive a password from the given parameters according to the "Master Password" algorithm (http://masterpasswordapp.com/algorithm.html)
-  Given parameters (in order) are:
-      `counter` (starting with 1), `password_type` (maximum, long, medium, short, basic, or pin), `password`,
-       `user`, and `site`. The following line generates a long password for the user "user" and with a master-password "password"  on the site "example.com":
-       ```
-       {{ derivePassword 1 "long" "password" "user" "example.com" }}
-       ```
-
-## SemVer Functions:
-
-These functions provide version parsing and comparisons for SemVer 2 version
-strings.
-
-- semver: Parse a semantic version and return a Version object.
-- semverCompare: Compare a SemVer range to a particular version.
-
 ## Principles:
 
 The following principles were used in deciding on which functions to add, and
