+#!/bin/sh
+# 
+# This script is used to add and remove our extension from one of the Mozilla
+# products directory, and is run from 'triggers' when the product is installed or
+# upgraded, as well as when our package is installed. It is needed because
+# Mozilla products are installed into versioned directories in /usr/lib[64]/<product>
+# so we have to make a new symlink into the right directory when the
+# application is installed or upgraded. But we would rather not leave
+# our old symlinks behind, since that will cause the application
+# directories not to be removed. (flash-player leaves its old symlinks behind,
+# but that's no excuse for us to do the same...)
+#
+# Because I don't know any way of finding out what the new version
+# is on installation or old version on uninstallation, we have
+# to do things in a somewhat non-intuitive way
+#
+# The order on upgrade of the mozilla application is:
+#
+#  1. new package installed
+#  2. triggerin for new package - we add all symlinks
+#  3. triggerun for old package - we remove all symlinks
+#  4. old package uninstalled
+#  5. triggerpostun for old package - we add all symlinks
+#
+# Triggers are also run on self-upgrade, in that case we do:
+#
+#  1. new package installed
+#  2. triggerin for new package - we add all symlinks
+#  3. triggerun for old package - we remove all symlinks
+#  4. old package uninstalled
+#  5. postun for old package - we add all symlinks
+#  6. triggerpostun for old package - NOT RUN (contrary to RPM docs)
+#
+#
+# Script arguments:
+# --appname: the mozilla application that this extension should register into.
+#            Usually firefox or thunderbird.
+# --extname: the name of the extension. It can be determined by looking at
+#            the install.rdf file, in the extension directory. This file
+#            contains several <em:id> tags. The extname parameter is the
+#            content of the em:id tag which is not contained in the
+#            em:targetApplication tag
+# --extpath: the path where the extension will be installed
+# --action:  either "install" or "remove"
+# --basedir: the dirname of the directory where the target application is
+#            installed. Usually /usr/lib or /usr/lib64>, it defaults to
+#            /usr/lib
+#
+#
+# Here's an example implementation in rpm scriptlets:
+#
+# %define tbupdate %{_libdir}/lightning/mozilla-extension-update.sh --appname thunderbird --extname {e2fda1a4-762b-4020-b5ad-a41df1933103} --basedir %{_libdir} --extpath %{_libdir}/lightning --action 
+# 
+# %post
+# %{tbupdate} install || true
+# 
+# %preun
+# # On removal (but not upgrade), remove the extention
+# if [ $1 = 0 ] ; then
+#     %{tbupdate} remove || true
+# fi
+# 
+# %postun
+# # This is needed not to reverse the effect of our preun, which
+# # is guarded against upgrade, but because of our triggerun,
+# # which is run on self-upgrade, though triggerpostun isn't
+# if [ $1 != 0 ] ; then
+#     %{tbupdate} install || true
+# fi
+# 
+# %triggerin -- thunderbird
+# %{tbupdate} install || true
+# 
+# %triggerun -- thunderbird
+# %{tbupdate} remove || true
+# 
+# %triggerpostun -- thunderbird
+# # Guard against being run post-self-uninstall, even though that
+# # doesn't happen currently (see comment above)
+# if [ "$1" != 0 ] ; then
+#     %{tbupdate} install || true
+# fi
