Pretty Printing objective C with GNU a2ps

a2ps includes a stylesheet for objective c, but it's not mapped to anything. Plus, the .m extension is mapped to "octave" files (which I guess is some music notation format system...).

To have a2ps recognise and nicely print your Objective C source files, you just need to make the following changes to /usr/share/a2ps/sheets/sheets.map

Search for "octave" and comment out those lines like so:

# octave files
#octave:	/*.octavescript/
#	/*.m/

Then add a line for objective c like so:

# objective C
objc: /*.m/

If you also want your header files to be highlighted with the objective c stylesheet (instead of the default c stylesheet), use the following entry instead:

# objective C
objc: /*.m/
      /*.h/
