+@node Entry Points
+@chapter Entry Points
+
+Calp has many different entry points. Each is implemented in a module
+residing under @code{calp entry-points}. Each such module @emph{must}
+export a @code{main} procedure, which should take a list of command
+line arguments (as a single parameter).
+
+When starting Calp from the command line, the @code{main} procedure
+located in @code{(calp main)} is called. That procedure parse it's own
+command line flags, up until the first non-flag argument. That word
+will be used to chose the actual entry point, which is then
+responsible for parsing the remaining command line flags.
+
+Information about global command line arguments can be accessed by
+running @command{calp --help}, and subcommands arguments through
+@command{calp @var{<subcommand>} --help}.
