Mo is a mustache template rendering software written in bash.  It inserts
environment variables into templates.

Simply put, mo will change {{VARIABLE}} into the value of that
environment variable.  You can use {{#VARIABLE}}content{{/VARIABLE}} to
conditionally display content or iterate over the values of an array.

Simple usage:

   mo [OPTIONS] filenames...

Options:

   --allow-function-arguments
         Permit functions to be called with additional arguments. Otherwise,
         the only way to get access to the arguments is to use the
         MO_FUNCTION_ARGS environment variable.
   -d, --debug
         Enable debug logging to stderr.
   -u, --fail-not-set
         Fail upon expansion of an unset variable. Will silently ignore by
         default. Alternately, set MO_FAIL_ON_UNSET to a non-empty value.
   -x, --fail-on-function
         Fail when a function returns a non-zero status code instead of
         silently ignoring it. Alternately, set MO_FAIL_ON_FUNCTION to a
         non-empty value.
   -f, --fail-on-file
         Fail when a file (from command-line or partial) does not exist.
         Alternately, set MO_FAIL_ON_FILE to a non-empty value.
   -e, --false
         Treat the string "false" as empty for conditionals. Alternately,
         set MO_FALSE_IS_EMPTY to a non-empty value.
   -h, --help
         This message.
   -s=FILE, --source=FILE
         Load FILE into the environment before processing templates.
         Can be used multiple times.
   --    Indicate the end of options. All arguments after this will be
         treated as filenames only. Use when filenames may start with
         hyphens.

Mo uses the following environment variables:

MO_ALLOW_FUNCTION_ARGUMENTS - When set to a non-empty value, this allows
    functions referenced in templates to receive additional options and
    arguments.
MO_CLOSE_DELIMITER - The string used when closing a tag. Defaults to "}}".
MO_CURRENT - Variable name to use for ".".
MO_DEBUG - When set to a non-empty value, additional debug information is
    written to stderr.
MO_FUNCTION_ARGS - Arguments passed to the function.
MO_FAIL_ON_FILE - If a filename from the command-line is missing or a
    partial does not exist, abort with an error.
MO_FAIL_ON_FUNCTION - If a function returns a non-zero status code, abort
    with an error.
MO_FAIL_ON_UNSET - When set to a non-empty value, expansion of an unset env
    variable will be aborted with an error.
MO_FALSE_IS_EMPTY - When set to a non-empty value, the string "false" will
    be treated as an empty value for the purposes of conditionals.
MO_OPEN_DELIMITER - The string used when opening a tag. Defaults to "{{".
MO_ORIGINAL_COMMAND - Used to find the `mo` program in order to generate a
    help message.
MO_PARSED - Content that has made it through the template engine.
MO_STANDALONE_CONTENT - The content that preceeded the current tag. When a
    standalone tag is encountered, this is checked to see if it only
    contains whitespace. If this and the whitespace condition after a tag is
    met, then this will be reset to $'\n'.
MO_UNPARSED - Template content yet to make it through the parser.
