Blatantly stealing the idea from Github, but not as fully implemented.

This is a little ugly due to the global config object. Boo.

Prevents `Copying pristine' messages in output with darcs pre-2.5.

String exceptions are deprecated and will soon no longer be supported at all.

Most of the instances of string exceptions in our code were not meant to be
catched, but just to get meaningful backtraces.

This patch replaces them with appropriate, usually generic, exceptions that
serve the same purpose.

With this, darcsweb can list the full darcs repo log.

Otherwise, we pay for the pygments import (which is noticeable) on every
darcsweb page view.

This follows the lazy module loading that is already being done for other
costly modules (i.e. 're').

When a multidir directory is not really a directory or a valid symlink to one,
we want to skip it instead of exploding.

This patch fixes that by doing a simple sanity check while processing the
configured multidirs.

Thanks to Ralph Giles <giles@ghostscript.com> for the report and the patch.

Very old darcs commits use a different time format, that leaks out in some
operations like annotate. This patch makes darcsweb able to handle it.

Thanks to Simon Michael <simon@joyful.com> for the report and the help.

A very simple change, makes the code more straightforward.

darcs 2 doesn't like files beginning with / as parameters for annotate. Since
darcs 1 doesn't care, remove the '/' before running darcs.

In darcs 2, there is no _darcs/inventory, so use the patches directory to find
out the last modification time of the repository.

Thanks to Patrick Waugh (ptwaugh@gmail.com) for providing (and testing) this
fix.

It can be used to avoid clashes in multidir entries.

Thanks to Dan Muller for the idea and alternative implementation.

- useful when hosting multiple darcsweb sites via vhost

Add it second place, so it goes after '.' but before the normal path. This
allows per-directory config files (desirable for multiple darcsweb
installations on the same machin), and avoids name clashing if there's a
config.py in the standard path.

This was reported by Philipp Kern <pkern@debian.org> in Debian bug 399751
(http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=399751).

This patch fixes RSS feed links when browsing darcsweb via SSL.

When the darcsweb URL is automatically detected, the script name is included in the URL - this results in bad links in RSS feeds like /darcsweb.cgi/darcsweb.cgi?r=projname.

Repositories in subdirectories have backslashes in their path when running on Windows, which results in bad URLS - replaced these with forward slashes.

* the annotate feature is still enabled by default
* this can be useful on slow machines

it is disabled by default and an example for cia is included

This patch adds a check to verify that the python version is >= 2.3, so the
user doesn't get strange errors when using older python interpreters.
Thanks to Mark Stosberg for the suggestion.

Add an option to replace text in the summary, using regexps. This allows you
to configure darcsweb to automatically detect and put links to other commits
or bug numbers.

This patch is heavily based on the one written by Kirill Smelkov
(kirr@mns.spb.ru).
