 They are typed as such (from cmds.h):
 /* Types for module command entry and help */
-typedef int * (* mod_entry_t)(char **);
-typedef void * (* mod_help_t)(unsigned int);
+typedef int (* mod_entry_t)(char **);
+typedef void (* mod_help_t)(unsigned int);

-typedef void * (* builtin_help_t)(unsigned int);
+typedef int (* builtin_entry_t)(char **, cliuser_t *);
+typedef void (* builtin_help_t)(unsigned int);
 As you can see, both modular and builtin commands expect an array of
 arguments, however bulitins also expect to be pointed to cliuser_t.

 : Change your "usage()" command as shown:
      -- void usage(...)
-     ++ void * help_cmd_foo(unsigned int level)
-     -- return;
-     ++ retrn CMD_VOID;
+     ++ void help_cmd_foo(unsigned int level)
      'level' is either 0 or 1, indicating the level of help requested.
      If the help / usage function currently exits based on how it is
 ,33 → 161,19
 : Change the programs "main()" as shown:
      -- int main(int argc, char **argv)
-     ++ int * cmd_foo(char **argv)
+     ++ int cmd_foo(char **argv)
      -- return 1;
      ++ return CMD_FAILURE;
      -- return 0;
      ++ return CMD_SUCCESS;
-     If main() returns an int that is not 1 or 0 (e.g. 127), cast it as
-     such:
-     -- return 127;
-     ++ return (int *) 127;
-     NOTE: _ONLY_ the main and help entry points need to return int * or
-     void *, respectively. Also take note that argc has changed. The type
-     for entry points may soon change.
      NOTE: If main is void, you'll need to change it and ensure that its
      expecting an array of arguments, even if they'll never be read or
      used. I.e.:
      -- void main(void)
-     ++ int * cmd_foo(char **argv)
+     ++ int cmd_foo(char **argv)
-     Similararly, do not try to return CMD_VOID within the modules main
-     entry point. If somehow you escape the compiler yelling at you, you
-     will surely see pretty blue and yellow fireworks once its reached.
 : Don't expose more than the entry and help points:
      -- void my_function(int n)
      ++ static void my_function(int n)

+ *
+ * Apart from precise values, GSP_DEFAULT allows to catch general cases.
+ * I.e. if we knew that after 0x1b 0x4f there always follow two more
+ * scancodes, we can define (0x1b, 0x4f, GSP_DEFAULT, GSP_DEFAULT, GSP_END)
+ * with null output. This will force the parser to read the entire sequence,
