Added perl interface.

1998-06-21  Martin Baulig  <martin@home-of-linux.org>

	* perl/*: Added perl interface.

	* sysdeps/linux/cpu.c: Bug fix.

	* include/glibtop/global.h: Only including guile header files
	within libgtop.

	* configure.in (LIGBTOP_LIBS): Added `-lgtop'.

	* Makefile.am: Creating `perl/Makefile.PL' from `perl/Makefile.PL.in'
	and `perl/Libgtop.xs' using `perl/perl.awk'.
