+Convert specified subversion xml logfile to GNU-style ChangeLog.
+
+Options:
+  -p, --prefix=REGEXP  set root directory of project (it will be striped off
+                       from ChangeLog entries, paths outside it will be 
+                       ignored)
+  -x, --exclude=DIR    exclude DIR from ChangeLog (relative to prefix)
+  -o, --output         set output file (defaults to 'ChangeLog')
+  -d, --domain=DOMAIN  set default domain for logins not listed in users file
+  -u, --users=FILE     read logins from specified file
+      --users-charset=ENCODING
+                       specify encoding of users. defaults to ISO8859-1
+  -F, --list-format    format commit logs with enumerated change list (items
+                       prefixed by '- ')
+  -r, --relocate=X=Y   before doing any other operations on paths, replace
+                       X with Y (useful for directory moves)
+  -D, --delta=SECS     when log entries differ by less then SECS seconds and
+                       have the same author -- they are merged, it defaults
+                       to 180 seconds
+  -h, --help           print this information
+
+Users file is used to map svn logins to real names to appear in ChangeLog.
+If login is not found in users file "login <login@domain>" is used.
+
+Example users file:
+john    John X. Foo <jfoo@example.org>
+mark    Marcus Blah <mb@example.org>
+
+Typical usage of this script is something like this:
+
+  svn log -v --xml | %s -p '/foo/(branches/[^/]+|trunk)' -u aux/users
+  
+Please send bug reports and comments to author:
+  Michal Moskal <malekith@pld-linux.org>
