+ (description
+ "Guile-SMC is a state machine compiler that allows to describe finite
+state machines (FSMs) in Scheme in terms of transition tables. It is capable
+to generate such transition tables from a @url{https://plantuml.com/,
+PlantUML} state diagrams.
+
+A transition table can be verified and checked for dead-ends and infinite
+loops. Also Guile-SMC FSMs gather statistics when they run.
+
+Guile-SMC comes with a Scheme program called @command{smc} -- a state machine
+compiler itself. It produces a Scheme code for an FSM from the PlantUML
+format. This tool is meant to be called on a PlantUML file when a program
+with a FSM is being built (for example, from a Makefile.)")
