# Note: I use a program I wrote, efl-version, to determine efl version
#       and I am assuming the efl version is the same as the efreet version
#       perhaps not necessarily true on debian (others?) where it is possible to
#       install efl compontents separately.
#       In the event that efl-version is not installed (in PATH) this program will
#       fallback on pkg-config and assumes it as well as efl development files are installed.

# I don't deal with non debian/standard --prefix instaations
# should I kill efreetd first, is that even possible as it restarts...
# FIXME: do I need to delete subdirs_$USER-VirtualBox.eet also
# I only handle/test archs i686 and x86_64, unsure how it acts on other archs
