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