+NAME
+    Text::Password::Pronounceable - Generate pronounceable passwords
+
+SYNOPSIS
+      # Generate a pronounceable password that is between 6 and 10 characters.
+      Text::Password::Pronounceable->generate(6, 10);
+
+      # Ditto
+      my $pp = Text::Password::Pronounceable->new(6, 10);
+      $pp->generate;
+
+DESCRIPTION
+    This module generates pronuceable passwords, based the the English
+    digraphs by D Edwards.
+
+HISTORY

+
+    CPAN module by Chia-liang Kao 9/11/2006. Perl cleaned up a bit by Jesse
+    Vincent 1/14/2001. Converted to perl from C by Marc Horowitz, 1/20/2000.
