+Subject: Configure CPAN::Distribution with correct name of html2text
+
+Bug-Debian: http://bugs.debian.org/640479
+Patch-Name: debian/find_html2text.diff
+
+If you use cpan from Debian you usually wind up trying to read online
+documentation through it. Unfortunately cpan can't find the
+html2text.pl script even though it is installed using the Debian
+package 'html2text'.
+
+Please see the attached patch for a quick fix of this issue.
+
+[Maintainer's note: html2text in Debian is not the same implementation
+as the html2text.pl which is expected, but should provide similar
+functionality].
