best way to install non debian package

["François" Chenais <francois@chenais.net>]

Hello, 


	What's the best way to install package which are not(yet) in debian
	package format or in the current distribution ?

	For example, I need pilot-link > 0.10.0 to use with palm m125
	but have no deb package.

	In which directory may I install it ?
	What's the Debian philosophy ?


	Thanks
