# verify-win32-save.sh - Save gate for the Win32 port: a save outlives the
# program, beside it.
#
# SAVE.EXE (examples/save) counts its launches in SAVES\RUNS.DAT. It is run
# twice under Wine from a scratch folder, started from another directory so
# the port's own move into the program's folder is what puts SAVES there;
# after the second run the count must be 2.
#
# Usage:   scripts/verify-win32-save.sh
# Requires: Wine; build/win32/bin/SAVE.EXE (make win32).
