# gcc(1) completion -*- shell-script -*-
#
# The only unusual feature is that we don't parse "gcc --help -v" output
# directly, because that would include the options of all the other backend
# tools (linker, assembler, preprocessor, etc) without any indication that
# you cannot feed such options to the gcc driver directly. (For example, the
# linker takes a -z option, but you must type -Wl,-z for gcc.) Instead, we
# ask the driver ("g++") for the name of the compiler ("cc1"), and parse the
# --help output of the compiler.
