since included a 'stripped down copy of glib 2.0') Since then we have worked on
improving pkg-config for embedded use.
## usage
Implementations of pkg-config, such as pkgconf, are typically used with the Implementations of pkg-config, such as pkgconf, are typically used with the
PKG_CHECK_MODULES autoconf macro. As far as I (nenolod) know, pkgconf is PKG_CHECK_MODULES autoconf macro. As far as we know, pkgconf is
compatible with all known variations of this macro. pkgconf detects at compatible with all known variations of this macro. pkgconf detects at
runtime whether or not it was started as 'pkg-config', and if so, attempts runtime whether or not it was started as 'pkg-config', and if so, attempts
to set program options such that its behaviour is similar. to set program options such that its behaviour is similar.

can run:
$ export PKG_CONFIG=/usr/bin/pkgconf
