What is "hg purge"?
===================
"purge" is a simple extension for the Mercurial source control management
system (http://www.selenic.com/mercurial).
This extension adds a "purge" command to "hg" that removes files not known
to mercurial, this is useful to test local and uncommitted changes in the
otherwise clean source tree.

This means that Mercurial will delete:
 - Unknown files: files marked with "?" by "hg status"
 - Ignored files: files usually ignored by Mercurial because they match a
   pattern in a ".hgignore" file
 - Empty directories: infact Mercurial ignores directories unless they
   contain files under source control managment
But it will leave untouched:
 - Unmodified files tracked by Mercurial
 - Modified files tracked by Mercurial
 - New files added to the repository (with "hg add")

Be careful with "hg purge", you could irreversibly delete some files you
forgot to add to the repository. If you only want to print the list of
files that this program would delete use:
  hg purge -vn

"hg purge" was inspired by the "cvspurge" script contained in CVS utilities
(http://www.red-bean.com/cvsutils/).


How to install
==============
Obviously you need an installed version of Mercurial to use this extension.
"purge" has been tested with Mercurial 0.8.1 and 0.9 but it may work with
other versions as well.

Put the "purge.py" file in a directory of your choice. Enable the extension
inserting an instruction like "purge=/path/you/choose/purge.py" in the
"[extensions]" section of a configuration file read by "hg".

For instance if you installed the script in "/home/USER/hg-purge/", you
can create a file named  ".hgrc" in your home directory with the following
content:
  [extensions]
  purge=/home/USER/hg-purge/purge.py
Note that using "~/USER/hg-purge/purge.py" does not work with hg 0.9.

For more information on the configuration files see the man page for "hgrc":
  man 5 hgrc


How to use "hg purge"
