LTPlus
Line Trace Plus

This is a general usage raster to vector conversion tool.

It was developed concurrently with GRASS 4.1 and uses
datatypes specific to that version  of GRASS.

This source code is currently broken.
It is being provided at this barely working stage in the hope
of generating further discussion on its udpate and on overall
development.

The program will undergo several minor versions as it is fixed against
GRASS4.2.  At that time the version number will be ltp4.2
Later, as GRASS 5.x libraries are stablized the version will progress to 
ltp5.0

see HISTORY.txt and Recent_development98 for
updates from 4.1 grass related to 4.2 grass related

see TODO for projected path of this update.

see History.old for pre 1992 development history
