+formats, so you don't have to remember the flags for each archive command.
+Just use the same command for all your archive files, and they'll never
+frustrate you again.
+
+In addition to providing one command to handle many different archive types,
+@command{dtrx} also aids the user by extracting contents consistently.  By
+default, everything will be written to a dedicated directory that’s named
+after the archive.  dtrx will also change the permissions to ensure that the
+owner can read and write all those files.
+
+It currently supports tar, zip (including self-extracting .exe files), cpio,
+rpm, deb, gem, 7z, cab, rar, and InstallShield files.  It can also decompress
+files compressed with gzip, bzip2, lzma, xz, or compress.")
