== What’s new

=== [2005/12/02] 0.9.0 released
Initial release

== Environment

Langhelp depends on some tools.

I use Debian GNU/Linux and Emacs21.
Langhelp probably works other GNU/Linux or Unices.
Langhelp may work Windows environment (Meadow + Cygwin).

Langhelp does not compete against other document-lookup tools, but
langhelp INTEGRATES document-lookup tools.
The more you have tools, the more usefule langhelp is.
