If you add this option after the option --compare <project1> <project2>, then object properties (permissions, compile settings, directories, bitmaps, etc.)
are ignored in the project comparison.
Syntax:
--compare="<path of project file>" "<path of reference project file>" --ignoreproperties="true"|"false"
Example
Automation Builder.exe --compare "D:\proj\project1.project" "D:\proj\project2.project" --ignoreproperties="true"
