Guys, I have general purpose CLI in the works. It has following plusses:

1. Multi level, it means that it supports both nested shells 

   > route
   route> add ...
   route> list ...
   route> delete 
   route> set 
   route> whatever ..
   route> exit


   and commands issued from the top

   > route add ...
   > route list ...
   > route delete ...
   ...

2. Multi instances and multiple login levels

3. Command line editing and syntax prompts.

4. Can be used as batch file  processor.

4. It is not a full blown shell, so it is small and unobtrusive. 

Minuses - it is being written in C++ (it seems like this is a case
where C++ really shows advantages).

Unfortunately, I am preempted by more urgent matters :(. So, if there is 
an interest I can donate it and I can promise participation. 

Thanks,

Aleksey
