+    longDescription = ''
+       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.
+
+       In addition, the library includes a path-searching module. This allows an
+       application to provide completion and lookup of files located in UNIX
+       style paths. Although not built into the line editor by default, it can
+       easily be called from custom tab-completion callback functions. This was
+       originally conceived for completing the names of executables and
+       providing a way to look up their locations in the user's PATH environment
+       variable, but it can easily be asked to look up and complete other types
+       of files in any list of directories.
+
+       Note that special care has been taken to allow the use of this library in
+       threaded programs. The option to enable this is discussed in the
+       Makefile, and specific discussions of thread safety are presented in the
+       included man pages.
