<!-- Prepare a ParlaMint corpus for a release, i.e. fix known and automatically fixable errors in the source corpus -->
<!-- The script can be used for both corpora in original langauge(s) or for its MTed variant -->
<!-- Input is either lingustically analysed (.TEI.ana) or "plain text" (.TEI) corpus root file XIncluding the corpus components
     Note that .TEI still needs access to .TEI.ana as that it where it takes its word extents
     Output is the corresponding .TEI / TEI.ana corpus root and corpus components, in the dicrectory given in the outDir parameter
     If .TEI is processed, the corresponding TEI.ana directory should be given in the anaDir parameter
     STDERR gives a detailed log of changes.

     Changes to root file:
     - delete old and now redundant pubPlace
     - insert textClass if missing
     - fix some corpus-dependent (GB) orgs and affiliations 
     - fix sprurious spaces in text content (multiple, leading and trailing spaces)

     Changes to component files:
     - add meeting reference to corpus specific parliamentary body of the meeting, if missing
     - change div/@type for divs without utterances
     - remove empty notes
     - assign IDs to segments without them
     - in .ana remove body name tag if name contains no words
     - in .ana change tag from <w> to <pc> for punctuation
     - in .ana change UPoS tag from - to X
     - in .ana change lemma tag from _ to normalised form or wordform
     - in .ana change root syntactic dependency to dep, if node is not sentence root
     - in .ana change <PAD> syntactic dependency to dep
     - fix sprurious spaces in text content (multiple, leading and trailing spaces)
