maps: add the "exists" method to RevMap
This is a part of the bigger plan to get rid of reading or writing rev_map
directly without going through the RevMap class.
Before this patch, there is no easy way to know if the RevMap file exists
or not, so the revset functions "fromsvn" and "svnrev" choose to read the
rev_map file directly, and throw an exception if the file does not exist.
This patch adds the "exists" method that will be used in svnmeta next patch,
so these revset functions can test if the file exists without reading the
rev_map file directly.

.. -*-restructuredtext-*- ============ hgsubversion ============ hgsubversion is an extension for Mercurial that allows using Mercurial as a Subversion client. At this point, hgsubversion is usable by users reasonably familiar with Mercurial as a VCS. It's not recommended to dive into hgsubversion as an introduction to Mercurial, since hgsubversion "bends the rules" a little and violates some of the typical assumptions of early Mercurial users. Installation ------------ You need to have either have Subversion 1.5 (or later) installed along with either Subvertpy 0.7.4 (or later) or the Subversion SWIG Python bindings. You need Mercurial 2.0 or later. .. _mercurial: http://selenic.com/repo/hg .. _mercurial-stable: http://selenic.com/repo/hg-stable .. _crew: http://hg.intevation.org/mercurial/crew .. _crew-stable: http://hg.intevation.org/mercurial/crew-stable If you are unfamiliar with installing Mercurial extensions, please see the UsingExtensions_ page in the Mercurial wiki. Look at the example for specifying an absolute path near the bottom of the page. You want to give the path to the top level of your clone of this repository. .. _UsingExtensions: http://mercurial.selenic.com/wiki/UsingExtensions Before using hgsubversion, I *strongly* encourage you to run the automated tests. Just use nose_ if you have it (or ``easy_install nose`` if you want it), or use ``python tests/run.py`` to run the suite with the conventional test runner. Note that because I use nose, there's a lot of stdout spew in the tests right now. The important part is that all the tests pass. .. _nose: http://code.google.com/p/python-nose/ You can check that hgsubversion is installed and properly activated using the following command:: $ hg version --svn Mercurial Distributed SCM (version ...)
