* Signs a template file using a key from PEM file
*
* Usage:
- * ./sign1 <xml-tmpl> <pem-key>
+ * ./sign1 <xml-tmpl> <pem-key>
*
* Example:
- * ./sign1 sign1-tmpl.xml rsakey.pem > sign1-res.xml
+ * ./sign1 sign1-tmpl.xml rsakey.pem > sign1-res.xml
*
* The result signature could be validated using verify1 example:
- * ./verify1 sign1-res.xml rsapub.pem
+ * ./verify1 sign1-res.xml rsapub.pem
*
* This is free software; see Copyright file in the source
