+Topic: yet more on getopt (command line arguments)

+Two more messages, the first a followup to a previous posting, and

+The AT&T syntax standard (which getopt does not completely enforce)
+actually forbids both of these usages.  Options with arguments are not
+allowed to be bundled, and they must be separated from their arguments
+by a space.

+
+The few existing commands that use such a convention, notably tar(1), are
+(in my experience) the worse for it.  It's seriously error-prone.  I think
+the AT&T people did the right thing.

+Subject: here is getopt
+
+Here is the source for getopt(3), the function that should be in
+everybody's C program, and getopt(1), a program that uses it to
+make shell programs comprehensible and consistent. There are man
+pages for both. Please send these on to the mod. group. Thanks.
+
+[ I have hacked the following shell script slightly so that
+it doesn't extract directly into system source directories,
+rather into the current directory.  It should be assumed that
+this code comes with no warranty from me, Ian Darwin, or anyone
+else as to whether it accurately represents getopt as distributed
+with System V, or any command line standard, or that it works
+at all, or that it will cause no damage when extracted or used. -mod]
