* certificates management policies for another crypto library may break it.
*
* Usage:
- * sign3 <xml-doc> <pem-key>
+ * sign3 <xml-doc> <pem-key>
*
* Example:
- * ./sign3 sign3-doc.xml rsakey.pem rsacert.pem > sign3-res.xml
+ * ./sign3 sign3-doc.xml rsakey.pem rsacert.pem > sign3-res.xml
*
* The result signature could be validated using verify3 example:
- * ./verify3 sign3-res.xml rootcert.pem
+ * ./verify3 sign3-res.xml rootcert.pem
*
* This is free software; see Copyright file in the source
* distribution for preciese wording.
