# User Thunderbird Profile Adoptions #

# different and complicated way. We simply need to ensure that the #
# Thunderbird binary is finding the existing profiles in the folder #
# $(HOME)/.thunderbird folder or a valid symlink pointing to the profiles. #
# #
# To "migrate" an old existing Icedove profile we can simply do a symlink #
# from $(HOME)/.thunderbird --> $(HOME)/.icedove . #
# #
# Afterwards do some changes to the file mimeTypes.rdf within every #
# profile. Also we can modify existing *icedove*.desktop entries in the #
# files. #
