"""Create a Fasta writer.
handle - Handle to an output file, e.g. as returned
by open(filename, "w")
wrap - Optional line length used to wrap sequence lines.
Defaults to wrapping the sequence at 60 characters
Use zero (or None) for no wrapping, giving a single
long line for the sequence.
record2title - Optional function to return the text to be
used for the title line of each record. By default
a combination of the record.id and record.description
is used. If the record.description starts with the
record.id, then just the record.description is used.
You can either use::
handle = open(filename, "w")
myWriter = FastaWriter(handle)
writer.write_file(myRecords)
handle.close()
Or, follow the sequential file writer system, for example:
handle = open(filename, "w")
myWriter = FastaWriter(handle)
writer.write_header() # does nothing for Fasta files
...
Multiple calls to writer.write_record() and/or writer.write_records()
...
writer.write_footer() # does nothing for Fasta files
handle.close()
