[TYPO3-english] Configuration for a custom EXT and his plugins

[Simone Paolinelli]

Hi to all.

I have wrote an extension that have 3 plugins.

For each plugin I give some configuration parameter via Typoscript (e.g. 
plugin.tx_myext_pi1.key1 = value) and I read the value in the plugin php 
code (e.g. $conf['key1']).

Many parameter are shared by all plugins and I have to copy the 
configuration for each plugin:

plugin.tx_myext_pi1.key1 = value
plugin.tx_myext_pi2.key1 = value
plugin.tx_myext_pi3.key1 = value
...

How can I set a set of common parameter which can be used by all plugin 
of extension?

Thanks in advance.

Simone
