! comparator log messages start with a line identifing comparator used, and date ran, and then a 
! sequence of 3 (sometimes 4) lines describing the differences found by comparator. 

! line 1      summary             type (canonical, archive, etc), bundle, and version info 
! line 2      comparison          exact repositories being compared
! line 3      reason              brief description of the differnce found (or errors or exceptions in processing)
! line 4      extraDetail         a bit more details about errors found (variable, only a few messages have 4 lines)
!
! Rules on which messages are significant, or unexpected, are specified as three regex expresssions, 
! one for each of 
! the (first) three lines above (the forth, "extra detail" is not considered). All three rules, must 
! "match" all three 
! lines. By carefully crafting the rules, you can get some rule to apply too all comparator messages, 
! (e.g. ignore any message 
! stating the about.mappings files are different) or ignore only a certain message for a a certain 
! bundle/version (e.g. 
! ignore differences in build.xml file, but only in the org.eclipse.jst.jsf.doc.user bundle). 
! Note that the three parts of a comparator message must match all three parts of an exclude rule, 
! but for simplicity, if a rule part is empty or null, it is interpreted to mean "match anything" for 
! that message part.
