Line 1,670:
* doing formatted I/O with Fortran is a pain... And unformatted does not mean ''free''; Fortran2003 has ''streams'', but they are not implemented (yet) in GNU Fortran compiler. Here (as in the write part) I've tried to handle the PPM format through formatted I/O. The tests worked but I have not tried still everything.
* comments after the first line are not handled
