# 'fdroid' is completed automatically, but aliases to it are not.
# For instance, to alias 'fd' to 'fdroid' and have competion available:
#
#	alias fd='fdroid'
#	complete -F _fdroid fd
#
# One can use completion on aliased subcommands as follows:
#
#	alias fbuild='fdroid build'
#	complete -F _fdroid_build fbuild
