- truncate unmappable sequence (rather than skipping) and show truncated subalignment

- if a feature can't be mapped, then add an empty entry to the GFF file (rather than skipping it entirely); implies --lazy

- report progress
PLEASE NOTE: While this program is reasonably fast if the GFF is properly ordered by chromosome and the start and end coordinates of features, it will be *very slow* if the GFF is not sorted. Assumes that the "seqid" or "name" field (the first field) of the GFF entries holds the chromosome name.
Note that the GFF specification defines coordinates to be 1-based and fully-closed, therefore representing the interval [start, end]. Conformance to this specification is assumed internally.
If requested, unmappable sequence will be truncated to the mappable portion; note that the truncation will favor the beginning of the requested sequence.
If a GFF feature is on the + strand for the source genome but the corresponding homologous region in the target genome is on the - strand, then the mapped GFF feature will be reported as on the - strand.
This manpage was written by Andreas Tille for the Debian distribution and can be used for any other usage of the program.
