A slightly more general but useful extension of this would be to use two 
labels, one for "import" and one for "export".  This would allow you to 
have multiple files/sessions that shared initial segments (i.e., 
file/session trees).  For example,

    <lp-code||common|body0>
    <lp-code|common|branch1|body1>
    <lp-code|common|branch2|body2>

would create two files/sessions with bodies body0+body1 and body0+body2. 
This would be more in line with languages that have the means to do 
#include's, and would also make possible a kind of "exploratory" 
session, where different approaches to the main line can be highlighted 
and developed without interfering with the main-line development.
