19Usage: ${self_basename} [options] file1 [file2 ...]
20
21This script generates a MSVC module definition file containing a list of symbols
22to export from a DLL. Source files are technically bash scripts (and thus may
23use #comment syntax) but in general, take the form of a list of symbols:
24
25  <kind> symbol1 [symbol2, symbol3, ...]
26
27where <kind> is either 'text' or 'data'
28
29
30Options:
31    --help                      Print this message
32    --out=filename              Write output to a file [stdout]
33    --name=project_name         Name of the library (required)
