Environemt for KDE programs started from the desktop icon

[Ryo Furue]

Hi KDEers,

| For example bash reads /etc/profile and its local equivalent when it
| is invoked as a login shell, but reads /etc/bash.bashrc and its
| local equivalent when run as an interactive shell, non-login, shell,
| so any environment customization in ~/.bashrc would be available in
| a Konsole window, but not for the KDE session itself.

And an easy solution is

   $ cd ~/.kde/env
   $ ln -s ~/.bash_profile  bash_profile.sh

if you set your environmental variables in ~/.bash_profile ,
and restart your KDE session.  Notice that filenames in
~/.kde/env/ should end with a ".sh" .

This solution is fairly clean, because .bash_profile is
executed only once.  (.bashrc is executed each time bash is invoked.)
When you don't use KDE, ~/.bash_profile is still executed because bash
executes it when it's invoked as a login shell.  This arrangement is
useful when you log in from a romte computer, for example.

One concern is that the startup script of the KDE system may override
some of the env. vars.  I wish the startup script executed the
~/.kde/env/ scripts at the very end of the startup process, but that
doesn't seem to be the case.  (Correct me if I'm wrong.)

Cheers,
Ryo
