To install gLib, xLib, and the mouse unit, just copy the *.TPU files 
to your \tp\units\ directory. Remember, if you make any modifications 
to the gLib source and have recompiled the units, you must copy the 
*.TPU files from your program directory (generally \tp\bin\) to 
\tp\units\. The *.TPU files have been compiled with Turbo Pascal 7.0, 
so users of different versions may have to recompile. gLib has only 
been tested with Turbo Pascal 7.0, though it should work on all other 
compilers that allow inline assembler and other cool stuff like that.
