LM-X licenses are text files, just like FlexNet/FLEXlm licenses. A typical LM-X license looks like the following example.

FEATURE my_app
\{
VENDOR = XFORMATION
VERSION = 1.0
END = 2015-03-27
LICENSEE = "COMPANY_ABC"
KEY = RNCLMCH561O4622J8JAA5U0EROSHD9RA22E5HOFEQSKVSTA5RO \
VGK7M5884EEI9V1PRB97BBAIH5AN4PU73LGUQDSDM
\}

LM-X has the same concept of features and vendors that FlexNet/FLEXlm does. However, the LM-X format is easier to understand, because everything is marked by specific keywords.
