+# NAME
+
+Alien::Tarql - Find or build Tarql (SPARQL for Tables)
+
+# SYNOPSIS
+
+Command line tool:
+
+    use Alien::Tarql;
+    use Env qw( @PATH );
+
+    unshift @PATH, Alien::Tarql->bin_dir;
+
+# DESCRIPTION
+
+This distribution provides Tarql so that it can be used by other
+Perl distributions that are on CPAN.  It does this by first trying to
+detect an existing install of Tarql on your system.  If found it
+will use that.  If it cannot be found, the source code will be downloaded
+from the internet and it will be installed in a private share location
+for the use of other modules.
