## This is a concatenation of the .m4 autoconf macro definition files for Guile and pkg-config.
## I bundled them together as one file "acinclude.m4" because otherwise I couldn't get aclocal to load them individually...
## Ian Holmes, 2/26/2010
## Autoconf macros for working with Guile.

# GUILE_PROGS -- set paths to Guile interpreter, config and tool programs
#
# Usage: GUILE_PROGS
#
# This macro looks for programs @code{guile}, @code{guile-config} and
# @code{guile-tools}, and sets variables @var{GUILE}, @var{GUILE_CONFIG} and
# @var{GUILE_TOOLS}, to their paths, respectively. If either of the first two
# is not found, signal error.
#
# The variables are marked for substitution, as by @code{AC_SUBST}.

# GUILE_FLAGS -- set flags for compiling and linking with Guile
#
# Usage: GUILE_FLAGS
#
# This macro runs the @code{guile-config} script, installed with Guile, to
# find out where Guile's header files and libraries are installed. It sets
# two variables, @var{GUILE_CFLAGS} and @var{GUILE_LDFLAGS}.
#
# @var{GUILE_CFLAGS}: flags to pass to a C or C++ compiler to build code that
# uses Guile header files. This is almost always just a @code{-I} flag.
#
# @var{GUILE_LDFLAGS}: flags to pass to the linker to link a program against
# Guile. This includes @code{-lguile} for the Guile library itself, any
# libraries that Guile itself requires (like -lqthreads), and so on. It may
# also include a @code{-L} flag to tell the compiler where to find the
# libraries.
#
# The variables are marked for substitution, as by @code{AC_SUBST}.
