Command Line Interface

[John Keyes <jb...@mac.com>]

I have just read a document[1] that details the recommended approach
to writing Java command lines.  I know that it is unlikely that ant will
change its command line interface but I was wondering what the general
approach to *recommended* standards are.  I know that just because
something is recommended it is not necessarily correct so please don't
get zealous about who has recommended this :-)

Cheers,

Itend to use the GNU standards. This basically consists of posix + extensions. 
ie allows long options (ala --help), allows consecutive short options (ie 
-abc == -a -b -c) and has a standard set of names to use. See

http://www.gnu.org/prep/standards_18.html

the trouble with the posix standard is that it works only if all attributes
are one letter long. go to two letters and the whole -abcd coalescing game
falls flat on its face.

So we choose to follow the other path, that of verbose parameters,
although -f is there for makefile consistency
