This program is used for inputting
4 types of Library information:

LINES, PCB DECALS, LOGIC DECALS,
and PARTTYPES

Lines are used to represent the Board
Outline, and user defined shapes such
as drill tables.

Part Decals are used to define components
pin locations and the Lines item used
to represent the partdecal's outline.

PartType defines the electrical properties
of a part. It also defines the partdecal
items used to draw the parts pins, the 
padstacks and component outlines.

We recommend that all user generated
libraries be backed up on a regular basis.
This will ensure that if the computer
loses power and causes the library to be 
corrupted you can replace it with a backup
copy. A list of files to be backed is 
listed below.

NOTE: STD may represent any user created
      library.

STD.LN -- Lines Library
STD.PD -- PCB PartDecal Library
STD.LD -- LOGIC PartDecal Library
STD.PT -- PartType Library
