#compdef 7z 7za 7zr 7zz
# this covers both the official 7-zip and the now deprecated p7zip (but not the
# p7zip command, which is a gzip-like wrapper)
#
# notes:
# - seemingly all 7zip commands, options, and option arguments are
# case-insensitive. we only partially support this
# - most options only work with certain commands. the html documentation lists
# which ones, but it was so consistently wrong or contradictory that i gave up
# on trying to separate them. do not blindly trust the documentation on this
