+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.
+
+Learn more about mustache templates at https://mustache.github.io/
+
+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. The file must be a valid shell script
+         and should only contain variable assignments.
+   -o=DELIM, --open=DELIM
+         Set the opening delimiter. Default is "{{".
+   -c=DELIM, --close=DELIM
+         Set the closing delimiter. Default is "}}".
+   --    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 "}}".
+    Used internally.
+MO_CLOSE_DELIMITER_DEFAULT - The default value of MO_CLOSE_DELIMITER. Used
+    when resetting the close delimiter, such as when parsing a partial.
+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 "{{".
+    Used internally.
+MO_OPEN_DELIMITER_DEFAULT - The default value of MO_OPEN_DELIMITER. Used
+    when resetting the open delimiter, such as when parsing a partial.
+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 unparsed 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.
