After a long time, there is a significantly (?) improved pnm2ppa-1.10 release. Since most users now probably get pnm2ppa-1.04 through their Linux/other distribution, this release may not get as much testing as earlier ones. Please report *any* anomalies/bugs you notice, so they can be fixed before pnm2ppa-1.10 goes to the distributions! Thanks.
The improvements should mean better quality image printing; There is also a new --dpi300 option for 300dpi pnm input.
