### Chose some debug configuration options:
# -DDEBUG
#	Turn on really heavy debug output. This is written to 
#	/tmp/debug/{SCREEN,screen}.<pid>. Look at these files and quote 
#	questionable sections when sending bug-reports to the author.
# -DDUMPSHADOW
#	With shadow-pw screen would never dump core. Use this option if
#	you still want to have a core. Use only for debugging.
