-Subject: Re: command line arguments
-
-> > A group of bundled options may end with an option that has an argument.
-> 
-> This creates confusion in using C-Kermit when you want to send an image
-> file.  For example:
-> 
-> 	send -is filename     < ---  works fine
->         send -si filename     < ---  bombs the program
-
-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.
-
-> I would *much* prefer to bundle the flags, then
-> have those with arguments pick them up in the same order as the flags are
-> listed.
-
-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]
