SHORT DESCRIPTION OF processAB INSTALLATION

Find the executive version in http://www.eso.org/~qc/dfos/processAB.html.

- put processAB under $DFO_BIN_DIR
  put the example pgi's under $DFO_BIN_DIR

- put config.processAB under $DFO_CONFIG_DIR

- put processAB.h files under $DFO_DOC_DIR

- call processAB -h

- you will need to edit config.processAB: specify the plugin names (comment them in the beginning); 
  edit the section 4 carefully since that section determines the final name of each pipeline product,
  per PRO.CATG. This requires some work but pays off since the product name is then
  completely under your control.
