# ===========================================================================
#
# SYNOPSIS
#
# AX_LIB_ID3([ACTION-IF-TRUE], [ACTION-IF-FALSE])
#
# DESCRIPTION
#
# This macro will check for the existence of id3lib
# (http://id3lib.sourceforge.net/). It does this by checking for the
# header file id3.h and the id3 library object file. A --with-id3lib
# option is supported as well. The following output variables are set with
# AC_SUBST:
#
# ID3_CPPFLAGS
# ID3_LDFLAGS
# ID3_LIBS
#
# You can use them like this in Makefile.am:
#
# AM_CPPFLAGS = $(ID3_CPPFLAGS)
# AM_LDFLAGS = $(ID3_LDFLAGS)
# program_LDADD = $(ID3_LIBS)
#
# Additionally, the C preprocessor symbol HAVE_ID3LIB will be defined with
# AC_DEFINE if id3lib is available.
