- * Changelog
- * ~~~~~~~~~
- *
- * Thu, 22 Aug 2002 15:10:43 +0200
- * - Update Config.help entry. I got a number of emails asking
- * me to tell their senders if they could make use of this
- * piece of code... So: "SRM is something like BIOS for your
- * Alpha"
- * - Update code formatting a bit to better conform CodingStyle
- * rules.
- * - So this is v0.0.5, with no changes (except formatting)
- *
- * Wed, 22 May 2002 00:11:21 +0200
- * - Fix typo on comment (SRC -> SRM)
- * - Call this "Version 0.0.4"
- *
- * Tue, 9 Apr 2002 18:44:40 +0200
- * - Implement access by variable name and additionally
- * by number. This is done by creating two subdirectories
- * where one holds all names (like the old directory
- * did) and the other holding 256 files named like "0",
- * "1" and so on.
- * - Call this "Version 0.0.3"
- *
