#   Building Consed from source is error prone and not simple which is
#   why I provide executables.  Due to time limitations I cannot
#   provide any assistance in building Consed.  Even if you do not
#   modify the source, you may introduce errors due to using a
#   different version of the compiler, a different version of motif,
#   different versions of other libraries than I used, etc.  For this
#   reason, if you discover Consed bugs, I can only offer help with
#   those bugs if you first reproduce those bugs with an executable
#   provided by me--not an executable you have built.
# 
#   Modifying Consed is also difficult.  Although Consed is modular,
#   some modules are used by many other modules.  Thus making a change
#   in one place can have unforeseen effects on many other features.
#   It may takes months for you to notice these other side-effects
#   which may not seen connected at all.  It is not feasable for me to
#   provide help with modifying Consed sources because of the
#   potentially huge amount of time involved.
