+2001-03-07 Bruce Guenter <bruce@bruce-guenter.dyndns.org>
+
+ * Renamed cli.h to cli++.h
+
+2000-10-25 Bruce Guenter <bruce@bruce-guenter.dyndns.org>
+
+ * cli2pod.pl (parse_options): Ignore {0,} as well as {0}.
+
+2000-08-15 Bruce Guenter <bruce@bruce-guenter.dyndns.org>
+
+ * cli2pod.pl: Replaced the CLI documentation programs with this
+ script which outputs POD, which can be translated to man pages or
+ HTML (or LaTeX, or text, or FM).
+
+2000-08-14 Bruce Guenter <bruce@bruce-guenter.dyndns.org>
+
+ * cli_parse.pl (parse_header_line): Rewrote the parsing to deal
+ with multi-line strings.
+
+ * cli2man.pl (synopsis): Add usage string.
+
+ * cli2html.pl (synopsis): Add usage string.
+
+2000-08-12 Bruce Guenter <bruce@bruce-guenter.dyndns.org>
+
+ * cli_parse.pl, cli2html.pl, cli2man.pl: Created these programs.
+
+2000-08-01 Bruce Guenter <bruce@bruce-guenter.dyndns.org>
+
+ * main.cc (show_option): Fixed several width glitches.
+
+2000-07-18 Bruce Guenter <bruce@bruce-guenter.dyndns.org>
+
+ * cli.h (struct cli_option): Added new uinteger type.
+
+ * main.cc (fill): Removed use of mystring.
+
+2000-07-13 Bruce Guenter <bruce@bruce-guenter.dyndns.org>
+
+ * Removed include of mystring.
+
+2000-01-09 Bruce Guenter <bruceg@daedalus.bfsmedia.com>
+
+ * main.cc (parse_short): Modified the logic here to treat a string
+ value immediately following a string option as the value for that
+ option rather than as more flags. This makes it behave much more
+ like the standard getopt library.
+
+1999-09-30 Bruce Guenter <bguenter@mikhail.qcc.sk.ca>
+
+ * main.cc (show_option): Changed stringlist option string from
+ "=LIST" to "=ITEM".
+
+1999-09-29 Bruce Guenter <bguenter@mikhail.qcc.sk.ca>
+
+ * main.cc (cli_option::set): Fixed problem with setting a string
+ list option.
+
+1999-09-11 Bruce Guenter <bguenter@mikhail.qcc.sk.ca>
+
+ * main.cc (show_help): Split off two parts of this routine into
+ calc_max_width and show_option.
+ (show_option): Add "=INT" for integer options, and don't add extra
+ space for non-value long options.
+ (set): Use strtol instead of atoi to parse the integer string, to
+ allow for error checking.
+ (show_option): Fixed handling of string lists.
+
+1999-08-14 Bruce Guenter <bguenter@mikhail.qcc.sk.ca>
+
+ * main.cc (set_argv0): Sets argv0 to the complete value of
+ argv[0], argv0dir to the part of argv[0] up to and including the
+ last '/' (or blank if there is none), and argv0base to the
+ remainder of argv[0]. This is for use in programs that determine
+ what to do based on the value of the program name.
+
+1999-07-14 Bruce Guenter <bguenter@mikhail.qcc.sk.ca>
+
+ * main.cc (parse_long_eq): Fixed to account for "counter" flag
+ type.
+ (parse_long_noeq): Fixed to account for "counter" flag type.
+ (parse_long_eq): set() will return one, but this shouldn't return
+ one, so subtract one from its result.
+ (show_help): Added a mechanism to display default values on a
+ second line.
+ (show_help): Output a blank line before the "--help" option line.
+
+1999-07-04 Bruce Guenter <bguenter@mikhail.qcc.sk.ca>
+
+ * main.cc (show_help): Only show a "=VALUE" for string and integer
+ option types.
+
+1999-06-30 Bruce Guenter <bguenter@mikhail.qcc.sk.ca>
+
+ * messages.cc (cli_error): Moved this routine into a separate
+ module, and added a "cli_warning" routine.
+
+1999-06-25 Bruce Guenter <bguenter@mikhail.qcc.sk.ca>
+
+ * main.cc (set): Added handling for two new option types: string
+ list and counters. A stringlist maintains a linked list of all
+ the given option arguments. A counter adds the flag_value to the
+ dataptr each time it is encountered.
+ (parse_short): Fixed faulty logic regarding options with values.
+ Need to merge parts into cli_option::set().
+
+1999-06-24 Bruce Guenter <bguenter@mikhail.qcc.sk.ca>
+
+ * main.cc: Rewrote the "help" option handling to stop it being a
+ special case, by making an internal option list that includes a
+ "help" option at the end of it.
+ (show_help): Cleaned up the option formatting to produce more
+ correct output.
+ (build_options): Removed the need to count the options. Note
+ that this breaks compatibility with previous versions.
+ (cli_error): Added this convenience function for the CLI program
+ to report errors and optionally exit.
+ (set): Added functionality to call functions when an option is
+ parsed, and moved some of the option parsing into class methods
+ from the structure.
+ (main): Moved the test for showing the usage information before
+ the test for counting command-line arguments.
