Usage: ${self_basename} [options] file1 [file2 ...]
This script generates a MSVC module definition file containing a list of symbols
to export from a DLL. Source files are technically bash scripts (and thus may
use #comment syntax) but in general, take the form of a list of symbols:
<kind> symbol1 [symbol2, symbol3, ...]
where <kind> is either 'text' or 'data'
Options:
--help Print this message
--out=filename Write output to a file [stdout]
--name=project_name Name of the library (required)
