payload.README

The plugins built using the GenericKnimeNodes functionality need the binary programs
executed by each node to reside in a payload directory containing special zip archives.
For each target platform (mac, lnx, win) there has to be a zip archive.

For each supported platform the payload directory should contain two files :

- binaries_<platform>_<wordsize>.ini - a ini file containing needed environment variables
- binaries_<platform>_<wordsize>.zip - a zip file containing a bin folder with executable 
  binaries, a lib folder with needed libraries and an optional data directory
  
Where <platform> is either: win, mac or lnx and <wordsize> 32 or 64.  



For Linux 64 bit systems as target a ini-file named 

binaries_lnx_64.ini

might look like :

LD_LIBRARY_PATH=$ROOT/lib/
DATA_PATH=$ROOT/data/
 
The corresponding binaries_lnx_64.zip content would look like this :

 bin/
  |
  +---  foo
  |
  +---- bar
 lib/
  |
  +---- baz.so
 data/
  |
  +---- data.dat 
  
 where foo and bar are executable binaries placed in the bin directory, baz.so is 
 a needed library that is placed in the lib directory. The data directory contains
 a file with some addtional data foo or bar might need during execution.
 
 
So fo each target OS and word size you need to prepare a corresponding pair of files
(binaries_<platform>_<wordsize>.ini,binaries_<platform>_<wordsize>.zip) that all reside
in a payload directory. The contents of the whole payload directory will be packaged
into the final plugin jar and (depending on the execution platform) will be extracted
upon execution on a host system.
