[Yanel-dev] Setting of YANEL_HOME

[Michael Wechner]

Hi

As recently described one can build resources (and realms) much more 
efficiently by using their specific build.xml files directly.

But in order to do so one needs to know where YANEL_HOME is. I am afraid 
that people do not use this since one needs to set YANEL_HOME explicitely.

So my suggestion is that we enhance the core build.sh (build.bat) in 
order to check for YANEL_HOME (just as it already checks for JAVA_HOME) 
and if it hasn't been set yet, either writes a message or sets it 
automagically, whereas I don't think automagic is very simple, because 
it depends very much on the OS and shell (in the case of UNIX).

Also I think it would make sense to validate YANEL_HOME, because it 
might be possible that one has two yanel sources on the same computer 
but at various locations and this can result in confusing builds.

WDYT?

Thanks

Michi
