o First pass at the regex code. lib/regex/matcher takes an array of regex's and builds a very efficient engine that will tell you which regex a string matches with only a single pass through the string. To be used in the config file when specifying devices. o Anchor's aren't supported yet (^ and $) but that won't take long. o Also when we get some realistic config files we may want to consider adding an extra level of indirection to the dfa state in order to compress the table. It all depends on how large typical tables get. 2001-10-19 18:36:57 +04:00			`/*`
