33 * Changelog
34 * ~~~~~~~~~
35 *
36 * Thu, 22 Aug 2002 15:10:43 +0200
37 * - Update Config.help entry. I got a number of emails asking
38 * me to tell their senders if they could make use of this
39 * piece of code... So: "SRM is something like BIOS for your
40 * Alpha"
41 * - Update code formatting a bit to better conform CodingStyle
42 * rules.
43 * - So this is v0.0.5, with no changes (except formatting)
44 *
45 * Wed, 22 May 2002 00:11:21 +0200
46 * - Fix typo on comment (SRC -> SRM)
47 * - Call this "Version 0.0.4"
48 *
49 * Tue, 9 Apr 2002 18:44:40 +0200
50 * - Implement access by variable name and additionally
51 * by number. This is done by creating two subdirectories
52 * where one holds all names (like the old directory
53 * did) and the other holding 256 files named like "0",
54 * "1" and so on.
55 * - Call this "Version 0.0.3"
56 *
