"Regexp patterns for matching links on a VCS web page.
The patterns are grouped by VCS web system type.
\\<mozadd-mirror-mode-map>
To make a new pattern you can do like this:
- Open the file in Firefox.
- View the buffer source in Emacs in some way.
- Turn on `mozadd-mirror-mode'.
- Use the command `mozadd-init-href-patten'.
- Then start `re-builder' to refine the pattern.
(Or, use isearch if you prefer that.)
- Use `ourcomments-copy-target-region-to-reb' for
easy copying from target buffer to re-builder.
- To see what you patterns matches in the web page
use `M-x mozadd-update-mozilla'.
- If the page looks terrible then add a <base href=...>
tag by doing `M-x mozadd-add-href-base'.
*Note: It is always sub match 1 from these patterns that are
used."

VCS-REC should be an entry like the entries in the list

If FILE-MASK is non-nil then it is used to match a file relative
path. Only matching files will be downloaded. FILE-MASK can
have two forms, a regular expression or a function.
If FILE-MASK is a regular expression then each part of the path
may be a regular expresion \(not containing /).
If FILE-MASK is a function then this function is called in each
directory under DL-ROOT. The function is called with the
directory as a parameter and should return a cons. The first
element of the cons should be a regular expression matching file
names in that directory that should be downloaded. The cdr
should be t if subdirectories should be visited.
If RECURSIVE go into sub folders on the web page and download
files from them too.
Place the files under DL-DIR.
The revision on the page page-URL should match DL-REVISION if this is non-nil.
If TEST is non-nil then do not download, just list the files"
