+achieved by using a database that contains genome-wide cross-species rankings
+for each motif.  The motifs that are then annotated to TFs and those that have
+a high @dfn{Normalized Enrichment Score} (NES) are retained.  Finally, for

+improved replacements for the shell scripts provided by GNU gzip.
+@command{ztest} tests the integrity of supported compressed files.
+@command{zupdate} recompresses files with lzip, similar to gzip's
+@command{znew}.
+
+Supported compression formats are bzip2, gzip, lzip, and xz.  Zutils uses
+external compressors: the compressor to be used for each format is configurable

 with FFmpeg.  A video acquired using a hand-held camera or a camera mounted on a

 as surfing, skiing, riding and walking while shooting videos are especially
 prone to erratic camera shakes.  Vidstab targets these video contents to help
 create smoother and stable videos.")
