-# This program wraps around pkg-config to generate the correct include and
-# library paths when cross-compiling using a sysroot.
-# The assumption is that the sysroot contains the .pc files in usr/lib/pkgconfig
-# and usr/share/pkgconfig (relative to the sysroot) and that they output paths
-# relative to some parent path of the sysroot.
-# This assumption is valid for a range of sysroots, in particular: a
-# LSB-compliant root filesystem mounted at the sysroot, and a board build
-# directory of a Chromium OS chroot.
-# Additional directories containing .pc files may be specified by setting
-# the PKG_CONFIG_PATH environment variable- these will be prepended to the
-# generated paths.
