LU is one of the early tools for the management of Novosielski library files (i.e. the .LBR files common in the CP/M world). I do not remember ever seeing the source code for a CP/M library tool that runs on CP/M. However there were compatible tools written for UNIX and MSDOS. This program is just a back-port from linux to CP/M. I modified the source to compile with Hi-Tech C. It compiles cleanly under CP/M and also on linux with the gcc toolset. I am a firm believer in having source code for things that I use so if ever the need should arise, I can fix or enhance them. This program represents one small step in the right direction. It doesn't mean that I abandon tools such as delbr or nulu for which I lack source code but it does mean that I am not dependent on them. Jon Saxton tesseract@triton.vg 22 Jul 2014
