#!bash
#
# fdroid completion support.
#
# 'fdroid' is aliased 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
#
# There's also a completion function made for aliases to 'fdroid build -p':
#
#   alias fbld='fdroid build -p'
#   complete -F _fdroid_build_project fbld
