+<title>How to fix the compile time error about missing confetti</title>
+<para>
+  An error about missing confetti:
+<programlisting>
+Generating prscfg.h, prscfg.c...
+[ 13%] Generating prscfg.h, prscfg.c
+/bin/sh: CONFETTI-NOTFOUND: not found
+</programlisting>
+This error is caused by cmake, trying to re-create generated files
+prscfg.h, prscfg.c in <filename>cfg/</filename> directory.
+These files are under revision control and normally need not to be 
+regenerated. 
+The fix is to
+<programlisting>
+<prompt>$ </prompt>git checkout cfg/prscfg.h
+<prompt>$ </prompt>git checkout cfg/prscfg.c
+<prompt>$ </prompt>touch cfg/prscfg.[hc]
+</programlisting>
+The other alternative, if you have actually modified
+<filename>core_cfg.cfg_tmpl</filename> is to install confetti from
+<link xlink:href="http://github.com/mailru/confetti"/> and let cmake use it.
