The tecla library provides UNIX and LINUX programs with interactive
command line editing facilities, similar to those of the UNIX tcsh
shell. In addition to simple command-line editing, it supports
recall of previously entered command lines, TAB completion of file
names or other tokens, and in-line wild-card expansion of
filenames. The internal functions which perform file-name completion
and wild-card expansion are also available externally for optional
use by programs.
