# etelpmoc is the reverse of complete: it de-serialises the tab completion
# request into the appropriate environment variables expected by the tab
# completion tools, performs whatever action is wanted, and serialises the
# result. It accomplishes this by having functions override the builtin
# completion commands.
#
# this always runs "inside", in the same environment you get when doing "snap
# run --shell", and snap-exec is the one setting the first argument to the
# completion script set in the snap. The rest of the arguments come through
# from snap-run --command=complete <snap> <args...>
