#
#  This script compiles a JSPWiki release.  ATM it's pretty much hardcoded to certain basic
#  assumptions (OSX, Europe, distributions go to ecyrd.com). We can fix these later.
#
#  Usage: build_jspwiki_distro.sh [branchname]
#
#  E.g. branchname can be "tags/jspwiki_3_0_0" or "branches/JSPWIKI_2_8_BRANCH" or "trunk". Default is "trunk".
#
#  You may set the following environmental variables before you invoke this script
#
#  DESTDIR : where the final deliverables are built
#  JAVA_HOME : where the java home is.
#
