# This script goes through all of the lib header files and creates a .def file
# for each DLL for Win32. It recurses as necessary through the subdirectories

# This program should only be run if it is necessary to regenerate
# the .def files. Normally these files should be updated by hand, adding
# new functions to the end and removing obsolete ones.
# If you do regenerate them you will also need to modify them by hand to
# to pick up those routines not detected by this program (like openlog).
