Subject: Racc error recovery

Hi everyone,

I'm writing a racc parser, and I need to recover from parse errors.
Basically I'm writing a CSS parser, and I need to handle poorly
formatted CSS.

Unfortunately I can't seem to find any good documentation or examples on
error recovery.  I've read the Racc documentation about on_error and
entering "error recovering mode", as well as calling yyerrok to leave
error recovering mode, but I don't know what that actually means.

I've also discovered the "error" rule, but I don't want to explicitly
add that rule to every rule that could possibly have an error.

Any tips would be greatly appreciated.  Thanks!
