# Slackware SlackBuild script 
# ===========================
# By:        Eric Hameleers <alien@slackware.com>
# For:       fuse
# Descr:     Filesystem in Userspace
# URL:       http://fuse.sourceforge.net/
# Needs:     kernel >= 2.6.9 . Note that a 2.4 kernel was only supported
#            up to release 2.5.3
# Changelog:
# 2.2-1:     04/mar/2005 by Eric Hameleers <alien@sox.homeip.net>
#            * Initial build.
# 2.2-2:     17/mar/2005 by Eric Hameleers <alien@sox.homeip.net>
#            * Separate kernel module into its own package.
# 2.4.2-1:   19/dec/2005 by Eric Hameleers <alien@slackware.com>
#            * Update. Proper parametrisation of kernel version
#              and kernel sourcedirectory. Fixed 'bin' group ownership of
#              the binaries. try to run 'depmod -a' and add
#              '/sbin/modprobe fuse' to rc.modules.
# 2.4.2-2:   23/dec/2005 by Eric Hameleers <alien@slackware.com>
#            * Fixed generation of the fuse-module-xxxxxx.txt file which is
#              basically the slack-desc- file. Also, added a "rm -rf $PKG2"
#              in the "--cleanup" section.
# 2.5.3-1:   01/Sep/2006 by Eric Hameleers <alien@slackware.com>
#            * Used new SlackBuild template.
# 2.6.3-1:   05/feb/2007 by Eric Hameleers <alien@slackware.com>
#            * Update so I can use it on 2.6.19+ kernels. Also, better detection
#              of the correct rc.modules to use. Make 'suid-root'ing the
#              fusermount binary configurable high up in the SlackBuild.
# 2.6.5-1:   22/jun/2007 by Eric Hameleers <alien@slackware.com>
#            * Update. Move binaries to /bin .
# 2.7.0-1:   30/jul/2007 by Eric Hameleers <alien@slackware.com>
#            * Update.
# 
# Run 'sh fuse.SlackBuild --cleanup' to build a Slackware package.
# The package (.tgz) plus descriptive .txt file are created in /tmp .
# Install using 'installpkg'.
