	3) Sequence Retrievial System (SRS).
	4) Efetch queries [default].

Efetch (default) ... Accession, Locus/Id
Srs (-s)         ... Accession, Locus/Id
Extern (-e)      ... Accession, Gi

Availables databases and www servers can be easily configured in the
program source file.

This program use a modified version of Alessandro Guffanti (guffanti@tigem.it)
PaintBlast package drawimage function, in order to display a graphical
alignment summary; this function has been rewrited and integrated in source
code for easier program installation and use. The PaintBlast original package
is available at <URL:http://hercules.tigem.it/Biomodules/PaintBlast.pm>.
It needs the perl GD.pm package too (interface to Thomas Boutell's gd library)
for image support (v1.20 or more for Png format, Gif otherwise).

This program has been already tested with:
- NCBI Blast 1.4.7 up to version 2.0.9
- Washington University Blast up to version 2.0a19
- GCG 9.1 blast.
