Modules update to 3.0.6-rko

[R.K. O. Ph.D. <rk...@ow...>]

Modules has once again been updated, bug-fixed, and hopefully improved
with 3.0.6-rko.

This version is the start of "module versioning",  that is, providing
a way to use different versions of modules.  Exactly, in the same
way that modules allows the user to use different versions of a
given package.  To understand how this is used, be sure to read
the INSTALL file.  There are also some changes for the user & system dot
files (look at the etc/skel & etc/global files).

This version also fixes bugs with "module swap" and with "module init*"
introduced with 3.0.4-rko,  which was a major rewrite to use higher
level Tcl RegExp routines.

The files have been uploaded to sunsite.unc.edu (currently in /incoming/Linux
and it should in the listed directory in a few days).

Primary-site:   sunsite.unc.edu		/pub/Linux/utils/shell/
Alternate-site: ftp.scruz.net		/users/rkowen/public/modules/

Here are the changes:

Modules 3.0.6-rko
Wed Feb 16 09:06:34 PST 2000		R.K. Owen (rk...@ow...)
	* Changed "unsetenv" to allow an optional third argument to
	  set the env.var. to when unloading.
	* Fixed bugs with and upgraded the "module init*" commands.
	* Added a preliminary RPM .spec file ... some of the versioning
	  changes conflict with some RPM features.
Modules 3.0.5-rko	(not meant for public release)
Fri Jan 21 18:59:18 PST 2000		R.K. Owen (rk...@ow...)
	* Changed the behavior if "module" is called without an argument.
	  In addition to the error message it prints out the help text.
	* Fixed a problem with module swapping. A test needs to be
	  added to the testsuite.
	* Rewrote many of the init files & modified modules to allow
	  one level of env.var. expansion in the MODULEPATH & MODULERCFILE
	  environment variables.  The purpose is to allow the co-existence
	  of many versions of the module command.
	  Only this & successive versions will implement this.
	* Got the --with-logging configure option actually doing something
	  in the code.  The default is no syslog-ing.
	  However, this affects the tests ... expect 3 failures originating
	  from testsuite/modules.50-cmds/100-loglevel.exp .
