program mkkeytab;

{
 This program takes the keyboard scan code definitions, (the const section
 of the rtl/unix/keyboard.pp file) and outputs a 
 latex table. The final output is done with some reformatting with the
 following sed commands:

 mkkeytab | sed 's/[aA]lt/ALT-/g' | sed 's/[Ss]hift/SHIFT-/g' | sed 's/[Cc]trl/CTRL-/g' > keys.tex
