# thunderbrand3 - a script to brand Thunderbird 3.0 without recompilation
#
# Based on firebrand script from http://bbs.archlinux.org/viewtopic.php?id=44320
# and thunderbrand script from archlinux-fr repository
#
# Currently works for en-US locale.  Modifications are necessary for other locales.
#
# This script replaces and changes (a few) files in an existing Thunderbird
# installation. Run it after a Thunderbird installation or upgrade, and restart
# Thunderbird. The program icon may not be (visibly) replaced until your desktop
# environment is restarted.
#
# To revert to the original brand, simply reinstall Thunderbird.
#
# Dependencies: wget, unzip, zip
#

THUNDERBIRDDIR=""                           # Where Thunderbird's data files resides. Usually something like /usr/lib/thunderbird-3.0.
                                            # If empty, autodetection is attempted.
NEWICONSDIR=""                              # If empty, the script uses a temporary directory for the replacement icons.
                                            # If you want to avoid downloading the icons every time you rebrand Thunderbird,
                                            # point NEWICONSDIR to a suitable directory.
SOURCEBASE="http://mxr.mozilla.org/comm-1.9.1/source/other-licenses/branding/thunderbird" # The URL under which the branding directory resides.
