A few months ago I was reading lots of SNMP MIBs (sming format), and 
wrote a parser using a Meta-2 derivative. However in the general case, 
and particularly for line-oriented input, it's probably a job for either 
regexes or an (as yet unwritten) equivalent to format() etc. However, 
error recovery (when a line departs from the accepted format part-way 
through) is not going to be easy.

What scripting languages can be embedded in FPC/Lazarus these days? If 
an embedded language was called for each line would the overhead be 
excessive?
