| Ausführliche Beschreibung | opt is a subroutine library which facilitates the convenient input
of parameters to a 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. It is similar to GNU's (and AT&T's old) getopts
package, but with a different interface that might be easier to use.
