  20 This script generates a MSVC module definition file containing a list of symbols
  21 to export from a DLL. Source files are technically bash scripts (and thus may
  22 use #comment syntax) but in general, take the form of a list of symbols:
  23
  24   <kind> symbol1 [symbol2, symbol3, ...]
  25
  26 where <kind> is either 'text' or 'data'
  27
  28
  29 Options:
  30     --help                      Print this message
  31     --out=filename              Write output to a file [stdout]
  32     --name=project_name         Name of the library (required)
