[cups.general] *.types, *.convs, filters, and cupsFilter

[Michael Sweet]

Right now you have two options:

1. If you are using CUPS 1.4.x, define a new application/vnd.hp-pcl MIME type with an additional "priority(100)" in it. That will override the existing application/vnd.cups-raw rule.
2. If you are using an earlier version of CUPS, edit the mime.types file and just remember to redo your changes when you upgrade...

>> sparing you all the long sad story as to the why, here is what I'm trying to accomplish.  I want CUPS to ALWAYS call a filter script, regardless of type.  it's working well except when I send a pcl type job, according to the mime.types as well as the c* file, it is matching as type application/vnd.cups-raw.  I can make this model work by commenting out that type from mime.types, but I really don't want to.  Ideas?  Here is my current config.  paultest is my filter name.  Eventually i'm going to fine tune my types, but I did the hand of god approach first to just try and catch them all.
