Usage

p2g - Turn Python into G-Code.Usage:  p2g [options]  <srcfile> [<dstfile>]  p2g help [ all | topics | maint | version | location | <topic> ]  p2g build-examples <dstdir>       p2g tram-rotary.py ~/_nc_/O{countdown}tr.nc        Makes an output of the form ~/_nc_/O1234tr.nc       p2g --func=thisone -        Read from stdin, look for the 'thisone' function and write to        to stdout.Arguments:  <srcfile>   Source python file.  <dstfile>   Destination G-Code file. [default: stdout]               {countdown} in file name creates a decrementing prefix               for the output file which makes looking for the .nc in               a crowded directory less painful - it's at the top.               (It's the number of seconds until midnight, so clear               the directory once a day.)  <topic>      [ all | topics | maint | version | location | <topic> ]         all      Print all readme.         topics   List all topics.         version  Show version         location Show absdir of main module.         <topic>  Print from readme starting at topic.Options:     --job=<jobname>      Olabel for output code.     --function=<fname>   Function to be compiled,                           default is last one in source file.     --narrow             Emit comments on their own line,                           makes text fit more easily into                           a narrow program window.     --short-filenames    Emit just the lsb of filenames.
