-#!/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
