# This file reflects the tireless work of
# Ilya Zakharevich <ilya@math.ohio-state.edu>
#
# Trimmed and comments added by 
#     Andy Dougherty  <doughera@lafcol.lafayette.edu>
#     Exactly what is required beyond a standard OS/2 installation?
#     There are notes about "patched pdksh" I don't understand.

# Note that symbol extraction code gives wrong answers (sometimes?) on
# gethostent and setsid.

# Note that during the .obj compile you need to move the perl.dll file
# to LIBPATH :-(
