20# This uses the same choices as csharpexec.c, but instead of relying on the
21# environment settings at run time, it uses the environment variables
22# present at configuration time.
23#
24# This is a separate shell script, because the various C# interpreters have
25# different command line options.

27# Usage: /bin/sh csharpexec.sh [OPTION] program.exe [ARGUMENTS]
28# Options:
29#   -L DIRECTORY      search for C# libraries also in DIRECTORY
