Deal with 2 different sources instead of just one - RefSeq_peptide & RefSeq_dna - since Mart needs one type per source.

Modified appropriate source_url entries as well.

fix bug that if -dumpcheck set and files not found then the script failed instead of dumping the files

Species-specific display_xref priorities for tetraodon. Same as in BasicMapper but Genoscope_* order reversed.

Make all external_synonym entries unique.

Corrected location from which display_xref .sql files are uploaded.

fix for no species being specified and more than one core database bring called (connection was not dropped)

Fixed calculation of transcript display_xrefs; wasn't considering translation-transcript relationship properly.

Now use | as separator character in composite hash keys; : was a bad choice since it appears in GO xrefs.

Don't write xref/object_xrefs for sources that have no corresponding external_db entry (but warn about this).

Set label to accession if it's not set otherwise (so that something gets displayed on the web site).

Check all object_xrefs are unique.

Still problem with gene display_xrefs.

Improved usage docs.

No longer write external_db table from source table, since external_db is defined in CVS. Now builds source_idd->external_db_id mapping and writes external_db_id to xref.txt.

Added external_db and version to core xref output.
