+%description
+TrouSerS is an implementation of the Trusted Computing Group's Software Stack
+(TSS) specification. You can use TrouSerS to write applications that make use
+of your TPM hardware. TPM hardware can create, store and use RSA keys
+securely (without ever being exposed in memory), verify a platform's software
+state using cryptographic hashes and more.
