/TEMPLATECMD [command [= [template]]]

Allows to define alias-commands, using templates.
/templatecmd
 Prints list of current template commands.
/templatecmd command
 Prints template, corresponding to specified command.
/templatecmd command =
 Destroys command.
/templatecmd command = template
 Defines new template command.
 Template may contain next special sequences:
  - $$  will be replaced with just $;
  - $*  will be replaced with all templatecmd args;
  - $0  will be replaced with templatecmd name;
  - $n  will be replaced with corresponding positional argument from command line.

Note: last detected argument will not be stripped from quotes and will contain all end of argument line.

Examples:
 * /templatecmd a = echo $2 $1 $5
   then "/a 1 2 3" will print "2 1"
   but "/a 1 2 3 4 5 6 7" will print "2 1 5 6 7".
 * /templatecmd b = echo $0 $*
   then "/b a b c d" will print "b a b c d"

Note: be careful not to cause endless loops!
