dnl @synopsis AC_CREATE_GENERIC_CONFIG [(PACKAGEnlibs [, VERSION])]
dnl
dnl Creates a generic PACKAGE-config file that has all the
dnl things that you want, hmm, well, atleast it has
dnl --cflags, --version, --libs. Ahhm, did you see ac_path_generic
dnl in the autoconf-archive? ;-)
dnl
dnl this macros saves you all the typing for a pkg-config.in script,
dnl you don't even need to distribute one along. Place this macro
dnl in your configure.ac, et voila, you got one that you want to install.
dnl
dnl oh, btw, if the first arg looks like "mylib -lwhat' then it
dnl will go to be added to the --libs, and mylib is extracted.
dnl
dnl the defaults: $1 = $PACKAGE $LIBS $2 = $VERSION
dnl there is also an AC_SUBST(GENERIC_CONFIG) that will be set to
dnl the name of the file that we did output in this macro. Use as:
dnl
dnl install-exec-local: install-generic-config
dnl
dnl install-generic-config:
dnl $(mkinstalldirs) $(DESTDIR)$(bindir)
dnl $(INSTALL_SCRIPT) @GENERIC_CONFIG@ $(DESTDIR)$(bindir)
