+ svn2cl.xsl - xslt stylesheet for converting svn log to a normal
+ changelog
+
+ 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 include-rev yes \
+ ++stringparam breakbeforemsg yes \
+ ++stringparam authorsfile FILE \
+ 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.
