Directories searched are /usr/java/* +# and /usr/local/java/*, which are assumed to be j{dk,re} installations. +# Apply the shell variable as you see fit. If sun changes things so +# <jre>/lib/plugin.jar is not the magic file it will stop working. +# +# This macro assumes that unzip, zipinfo or pkzipc is available (and can +# list the contents of the jar archive). The first two are assumed to work +# similarly enough to the infozip versisonms. The pkzipc version is +# assumed to work if I undertstand the documentation on pkware's site but +# YMMV. I do not have access to pwkware's version to test it. +# +# LICENSE +# +# Copyright (c) 2008 Duncan Simpson <dps@simpson.demon.co.uk> +# +# This program is free software; you can redistribute it and/or modify it +# under the terms of the GNU General Public License as published by the +# Free Software Foundation; either version 2 of the License, or (at your +# option) any later version. +# +# This program is distributed in the hope that it will be useful, but +# WITHOUT ANY WARRANTY; without even the implied warranty of +# MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.
