+Manage variables that can be substituted into roll commands.

+Examples: !get myvar, !set myvar 10
+
+!get <variable> = show variable of the given name
+!set <variable> <num> = set a variable to a number
+
+The !variables command will list all variables for the room. The
+variables command cna be used in a secure room to avoid spamming the
+actual room that the variable is set in.
+
+Variable names can be used in all types of dice rolls:
+
+!pool myvar + 3
+!roll myvar
+
+There are some limitations on variables: they cannot themselves be
+dice expressions (i.e. can only be numbers), and they must be uniquely
+parseable in an expression (i.e 'myvard6' does not work for the !roll
+command).
