LSF licenses are stored in a text file. The default name of the license file is license.dat.
The license.dat file for an LSF license normally contains the same products defined in lsf.cluster.cluster_name.
The license.dat file for a demo license contains a FEATURE line for each LSF product. Each feature contains an expiry date and ends with the string DEMO.
The FEATURE line contains an encrypted key to prevent tampering.
A demo license does not require a server daemon or vendor daemon, so it does not contain SERVER or DAEMON lines, only FEATURE lines.
