+of a fasta sequence file without spaces or headers and uses either a
+@code{mmap} in numpy binary format or @code{fseek}/@code{fread} so the
+sequence data is never read into memory.  It saves a pickle (@code{.gdx}) of
+the start and stop (for @code{fseek}/@code{mmap}) locations of each header in
+the fasta file for internal use.
+
+Note that this package has been deprecated in favor of @code{pyfaidx}.")
