Nick Craig-Wood bff702a6f1 docs: group the global flags and make them appear on command and flags pages
This adds an additional parameter to the creation of each flag. This
specifies one or more flag groups. This **must** be set for global
flags and **must not** be set for local flags.

This causes flags.md to be built with sections to aid comprehension
and it causes the documentation pages for each command (and the
`--help`) to be built showing the flags groups as specified in the
`groups` annotation on the command.

Short: `Checks the files in the source against a SUM file.`,

Checks that hashsums of source files match the SUM file.
It compares hashes (MD5, SHA1, etc) and logs a report of files which
don't match. It doesn't alter the file system.
If you supply the |--download| flag, it will download the data from remote
and calculate the contents hash on the fly. This can be useful for remotes
that don't support hashes or if you really want to check all the data.
Note that hash values in the SUM file are treated as case insensitive.
