#     * Version 1.1.2
#         By: Daenyth <Daenyth+arch _AT_ gmail _DOT_ com> April 2008
#         Changes:  Remove trailing slash from command line arguments to allow for tab completion on directories
#                   Notify the user as to the location of their completed package
#                   Remove the aur directory after we are done
#     * Version 1.1.1
#         By: Daenyth <Daenyth+arch _AT_ gmail _DOT_ com> April 2008
#         Changes:  Bugfix. Removed "local" declaration, since it's not a function
#                   Direct push/popd output to /dev/null
#     * Version 1.1.0
#         By: Daenyth <Daenyth+arch _AT_ gmail _DOT_ com> April 2008
#         Changes:  Preserve the build dir now and work elsewhere. 
#                   Honor /etc/makepkg.conf's BUILDSCRIPT variable.
#                   Also copy all $sources instead of just $BUILDSCRIPT.

# This will set $BUILDSCRIPT, which is usually PKGBUILD
eval `grep -m 1 BUILDSCRIPT /etc/makepkg.conf`
