line appears at the bottom instead of the top. The
indentation semantics of POD make the first item in
the (=over,=back) block look weird the other way.
- implemented a way to encode example usage into usage.h
One would define a macro called "${applet}_example_usage"
which would expand to the example text.
- The example usage is considered optional, but trivial and
full usage are not.
Here's an example using chown.
---- before
#define chown_trivial_usage \
"[OPTION]... OWNER[<.|:>[GROUP] FILE..."
#define chown_full_usage \
"Change the owner and/or group of each FILE to OWNER and/or GROUP.\n" \
"\nOptions:\n" \
"\t-R\tChanges files and directories recursively."
#define chown_example_usage \
"\t$ ls -l /tmp/foo\n" \
"\t-r--r--r-- 1 andersen andersen 0 Apr 12 18:25 /tmp/foo\n" \
"\t$ chown root /tmp/foo\n" \
"\t$ ls -l /tmp/foo\n" \
"\t-r--r--r-- 1 root andersen 0 Apr 12 18:25 /tmp/foo\n" \
"\t$ chown root.root /tmp/foo\n" \
"\tls -l /tmp/foo\n" \
"\t-r--r--r-- 1 root root 0 Apr 12 18:25 /tmp/foo\n"
---- after
=item I<chown>
chown [OPTION]... OWNER[<.|:>[GROUP] FILE...
Change the owner and/or group of each FILE to OWNER and/or GROUP.
Options:
-R Changes files and directories recursively.
Example:
$ ls -l /tmp/foo
-r--r--r-- 1 andersen andersen 0 Apr 12 18:25 /tmp/foo
$ chown root /tmp/foo
$ ls -l /tmp/foo
-r--r--r-- 1 root andersen 0 Apr 12 18:25 /tmp/foo
$ chown root.root /tmp/foo
ls -l /tmp/foo
-r--r--r-- 1 root root 0 Apr 12 18:25 /tmp/foo
-------------------------------
* make headers and footers for both the POD and SGML content
* make an SGML generator
* finish the command-line handling
Also, some of the documentation in usage.h will have to
be adjusted. expr needs some lines to be indented, and
ls has a stray comma. I may have missed some things...
but it looks OK for the most part.
- Added a section on avoiding dangerous, overrun-prone string functions, per
mailing list comment by David Douthitt
- Added comment on how to search-and-replace in multiple files per (very old)
mailing list comment by Larry Doolittle.
