+dtrx extracts archives in a number of different
+formats; 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.
+
+In addition to providing one command to handle many different archive
+types, 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.

+# HOW TO EDIT THIS FILE:
+# The "handy ruler" below makes it easier to edit a package description.
+# Line up the first '|' above the ':' following the base package name, and
+# the '|' on the right side marks the last column you can put a character in.
+# You must make exactly 11 lines for the formatting to be correct.  It's also
+# customary to leave one space after the ':' except on otherwise blank lines.
