#

# SYNOPSIS

#

#   AX_CREATE_PKGCONFIG_INFO [(outputfile, [requires [,libs [,summary [,cflags [, ldflags]]]]])]

#

# DESCRIPTION

#

#   Defaults:

#

#     $1 = $PACKAGE_NAME.pc

#     $2 = (empty)

#     $3 = $PACKAGE_LIBS $LIBS (as set at that point in configure.ac)

#     $4 = $PACKAGE_SUMMARY (or $1 Library)

#     $5 = $PACKAGE_CFLAGS (as set at the point in configure.ac)

#     $6 = $PACKAGE_LDFLAGS (as set at the point in configure.ac)

#

#     PACKAGE_NAME defaults to $PACKAGE if not set.

#     PACKAGE_LIBS defaults to -l$PACKAGE_NAME if not set.

#

#   The resulting file is called $PACKAGE.pc.in / $PACKAGE.pc

#

#   You will find this macro most useful in conjunction with

#   ax_spec_defaults that can read good initializers from the .spec file. In

#   consequencd, most of the generatable installable stuff can be made from

#   information being updated in a single place for the whole project.
