   8 Portability : POSIX

  10 Gargantext enables analyzing semi-structured text that should be parsed
  11 in order to be analyzed.
  12
  13 The parsers suppose we know the format of the Text (TextFormat data
  14 type) according to which the right parser is chosen among the list of
  15 available parsers.
  16
  17 This module mainly describe how to add a new parser to Gargantext,
  18 please follow the types.
