opt is:

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.
