perl script to extract tab delimited entries from Firebug's ConsoleExport html output
#!/usr/bin/perl
# quick, throwaway script to extract out info messages from the HTML dump of the
# firebug console which is produced by the ConsoleExport Firefox/Firebug

# I was interested in info message of the form.. so its pretty specific
# console.info("some label:87ms", 113, 200);
# TODO provide a way to extract log/warn/info/error/all entry types
