#
# Usage: GUILE_PROGS
#
# This macro looks for programs @code{guile}, @code{guile-config} and

# @var{GUILE_TOOLS}, to their paths, respectively. If either of the first two

# Usage: GUILE_FLAGS

# This macro runs the @code{guile-config} script, installed with Guile, to

# two variables, @var{GUILE_CFLAGS} and @var{GUILE_LDFLAGS}.

# 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.
