+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 --print
+
+To get the most recent version of "hg purge" visit its home page:
+  http://www.barisione.org/apps.html#hg-purge
+
+This program was inspired by the "cvspurge" script contained in CVS utilities
+(http://www.red-bean.com/cvsutils/).
+
+
+How to install
+==============
+The purge extension is distributed with Mercurial, to activate it you need to
+put these lines in your ~/.hgrc:
+
+  [extensions]
+  hgext.purge=
+
+For more information on the configuration files see the man page for "hgrc":
+  man 5 hgrc
+
+
+How to use "hg purge"
+====================
+For help on the usage of "hg purge" use:
+  hg help purge
