*
* The command syntax is
*	Calign file1 file2 [gap_limit [dist_limit]]
* where file1 and file2 contain arbitrary sequences of characters.  It is
* assumed that the two character strings are very similar.  Calign reports
* an alignment of the two sequences.
*
* The parameter gap_limit specifies that the insertion gaps
*                         of more than gap_limit symbols are
*                         penalized by gap_limit+1.
* The parameter dist_limit specifies the tolerable distance limit.
