+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.
