 pslMap - map PSLs alignments to new targets using alignments of
 the old target to the new target.  Given inPsl and mapPsl, where
 the target of inPsl is the query of mapPsl, create a new PSL
 with the query of inPsl aligned to all the targets of mapPsl.
 If inPsl is a protein to nucleotide alignment and mapPsl is a
 nucleotide to nucleotide alignment, the resulting alignment is
 nucleotide to nucleotide alignment of a hypothetical mRNA that
 would code for the protein.  This is useful as it gives base
 alignments of spliced codons.  A chain file may be used instead
 mapPsl.
 
-usage:
-   pslMap [options] inPsl mapFile outPsl
-
 Options:
   -chainMapFile - mapFile is a chain file instead of a psl file
   -swapMap - swap query and target sides of map file.
   -swapIn - swap query and target sides of inPsl file.
   -suffix=str - append str to the query ids in the output
    alignment.  Useful with protein alignments, where the result
    is not actually and alignment of the protein.
   -keepTranslated - if either psl is translated, the output psl
    will be translated (both strands explicted).  Normally an
    untranslated psl will always be created
   -mapFileWithInQName - The first column of the mapFile PSL records are a qName,
    the remainder is a standard PSL.  When an inPsl record is mapped, only
    mapping records are used with the corresponding qName.
   -mapInfo=file - output a file with information about each mapping.
    The file has the following columns:
