# To check before this hits the tree:
# 1. what bootstrap target actually does
# 2. whether gboostrap use flag is ok to be used as local use flag
# 3. Doc, what is going on there, what if latex is not installed,
#    what if pdf2ps is not installed etc.
# 4. more testing on configure flags
# 5. there is -O1 optimization flag, probably disables user's CFLAGS , bad
# 6. check if emacs configuration is correct
