-# This script runs pkg-config, optionally filtering out some results, and
-# returns the result.
-#
-# The result will be [ <includes>, <cflags>, <libs>, <lib_dirs>, <ldflags> ]
-# where each member is itself a list of strings.
-#
-# You can filter out matches using "-v <regexp>" where all results from
-# pkgconfig matching the given regular expression will be ignored. You can
-# specify more than one regular expression my specifying "-v" more than once.
-#
-# You can specify a sysroot using "-s <sysroot>" where sysroot is the absolute
-# system path to the sysroot used for compiling. This script will attempt to
-# generate correct paths for the sysroot.
-#
-# When using a sysroot, you must also specify the architecture via
-# "-a <arch>" where arch is either "x86" or "x64".
-#
-# CrOS systemroots place pkgconfig files at <systemroot>/usr/share/pkgconfig
-# and one of <systemroot>/usr/lib/pkgconfig or <systemroot>/usr/lib64/pkgconfig
-# depending on whether the systemroot is for a 32 or 64 bit architecture. They
-# specify the 'lib' or 'lib64' of the pkgconfig path by defining the
-# 'system_libdir' variable in the args.gn file. pkg_config.gni communicates this
-# variable to this script with the "--system_libdir <system_libdir>" flag. If no
-# flag is provided, then pkgconfig files are assumed to come from
-# <systemroot>/usr/lib/pkgconfig.
-#
-# Additionally, you can specify the option --atleast-version. This will skip
-# the normal outputting of a dictionary and instead print true or false,
-# depending on the return value of pkg-config for the given package.
