[developers] '@' in orthography, tsdb profiles

Hi Joshua,

The '@' character is used as a field separator in TSDB profiles.  I believe the correct escape sequence is '\s' (I'm sure Stephan will correct me if I'm wrong).

There is a program named "mkprof" that is bundled with the "art" tool, which does what you are describing (i.e. takes plain lines of text and creates a tsdb profile out of them that can be used for parsing -- including the escaping):


Good luck,
