I think the OP may have meant cmd.exe.  To discuss this topic further,
I think you need to distinguish the *shell* from the tty/console/editor
it runs inside of to display its input, etc.

You can easily get emacs-style command line editing.

The purpose of cygwin as a library is to enable the relatively easy
porting to Windows of many/most Unix programs.  Roughly speaking,
it translates Unix library/system calls into Windows calls.  It is not
possible to hide every difference, but it does a pretty good job of
offering a Unix-like environment to those familiar with Unix.

To that end, the typical "front end" is bash (a Unix shell) running
inside some terminal/screen program, typically mintty or the Windows
console, but if you run X, you can have xterm, etc.

I think maybe Andre was saying "you're very welcome to do that", i.e.,
"be my guest".  However, most program have "man" pages, as on Unix.

Cpan is a subsystem for loading perl libraries and building them.
cygwin has a setup utility for downloading already-built versions
of a considerable range of programs that are maintained by a group
of mostly volunteer maintainers.  There are even more programs
available via cygports, which has a similar download/setup utility.

bash has a builting help command, for giving terse/reminder help on
bash's own commands.  For other things, use the "man" command, for
example, "man ls" will give you the man page for ls, etc.

Hope this helps.  Not sure what you were expecting, but it sounds
a little different from what cygwin is aiming to deliver.  However,
maybe what cygwin does is what you want/need, even if you don't
clearly realize it yet ...
