.. END EXAMPLES
Add individual documentation pages for string's subcommands This adds string-x.rst for each subcommand x of string. The main page (string.rst) is not changed, except that examples are shown directly after each subcommand. The subcommand sections in string.rst are created by textual inclusion of parts of the string-x.rst files. Subcommand man pages can be viewed with either of: ``` man string collect man string-collect string collect <press F1 or Alt-h> string collect -h ``` While `string -h ...` still prints the full help.
