   svn2cl.xsl - xslt stylesheet for converting svn log to a normal
                changelog

   version 0.11

   Usage (replace ++ with two minus signs which aren't allowed
   inside xml comments):
     svn ++verbose ++xml log | \
       xsltproc ++stringparam strip-prefix `basename $(pwd)` \
                ++stringparam linelen 75 \
                ++stringparam groupbyday yes \
                ++stringparam separate-daylogs yes \
                ++stringparam include-rev yes \
                ++stringparam include-actions yes \
                ++stringparam breakbeforemsg yes/2 \
                ++stringparam reparagraph yes \
                ++stringparam authorsfile FILE \
                ++stringparam ignore-message-starting \
                svn2cl.xsl - > ChangeLog

   This file is based on several implementations of this conversion
   that I was not completely happy with and some other common
   xslt constructs found on the web.
