Usage: w32sims [-v] [-u] [-s] [-w] [-r VERSION] [-f filename] [buildonly]
       -v Verbose output
       -u Run 'git pull' before building
       -r Use the specified version string for filenames (defaults to git revision)
       -s Strip binaries before zipping them up.
       -w Crosscompile for Windows (requires mingw32)
       -f Filename format string (without extension). This can include a
          filepath (relative or absolute) May include the following special
          strings:
            <version> - Replaced by the revision (or version name if -r is
                        used)
            <target>  - Target shortname
            <YYYY>    - Year (4 digits)
            <MM>      - Month (2 digits)
            <DD>      - Day of month (2 digits - 0-padded)
            <HH>      - Hour of day (2 digits, 0-padded, 00-23)
            <mm>      - Minute (2 digits, 0-padded)
          The default filename is rockbox-sim-<target>-<version>
