+TIGER, or the 'tiger' scripts, is a set of Bourne shell scripts,
+C programs and data files which are used to perform a security audit
+of UNIX systems.  It is designed to hopefully be easy to use, easy to
+understand and easy to enhance.
+
+'tiger' incorporates checks primarily oriented towards Linux integrity
+including: md5sums checks installed files, (and it can call AIDE or
+Intergrit aswell), analysis of local listening processes, and then some.
+
+Tiger uses 'chkrootkit' for rootkit scanning if it's present.
+
+This SlackBuild will also verify the package's PGP signature
+if the following conditions are met:
+
+    - You have GnuPG installed
+    - You have the appropriate public PGP key (0xDC814B09)
+      in your trustedkeys.gpg keyring
+      (available at http://savannah.nongnu.org/people/viewgpg.php?user_id=7475)
+    - You have downloaded the sig file from
+      http://download.savannah.gnu.org/releases/tiger/tiger-${VERSION}.tar.gz.sig

+# 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 ':'.
