  20 # This uses the same choices as csharpcomp.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# compilers have
  25 # different command line options.
  26 #
  27 # Usage: /bin/sh csharpcomp.sh [OPTION] SOURCE.cs ... RES.resource ...
  28 # Options:
  29 #   -o PROGRAM.exe  or  -o LIBRARY.dll
  30 #                     set the output assembly name
  31 #   -L DIRECTORY      search for C# libraries also in DIRECTORY
  32 #   -l LIBRARY        reference the C# library LIBRARY.dll
  33 #   -O                optimize
  34 #   -g                generate debugging information
