REM Usage: dll2lib [32|64] some-file.dll
REM
REM Generates some-file.lib from some-file.dll, making an intermediate
REM some-file.def from the results of dumpbin /exports some-file.dll.
REM Currently must run without path on DLL.
REM (Fix by removing path when of lib_name for LIBRARY line below?)
REM
REM Requires 'dumpbin' and 'lib' in PATH - run from VS developer prompt.
