opt.h  version 3.17  -	User Include File for options package.

OPT is a subroutine library which facilitates the convenient 
input of parameters to a C or C++ program. Parameters are parsed 
from a command line, with further facilities for reading options 
from files, from environment strings, or from an interactive 
environment. The aim of the opt package is to permit programs to 
be both user- and programmer- friendly. The package attempts to 
on the one hand provide a direct and relatively full-featured 
input interface to the ultimate user of the program, and at the 
same time impose a minimal amount of work on the programmer to 
"attach" the package to his or her software. A texinfo file is 
part of the distribution; or you can view the html documentation at:
http://nis-www.lanl.gov/~jt/Software/opt/opt_toc.html
