//
//    MySimpleCompare.r
//
//    All files from this example are installed to folder "Simple Compare Example"
//    on the root of the selected target volume of the installation.
//
//    This script demonstrates installing two test files, one based on creation
//    date comparison, the other based on version comparison against target file.
//    Date for source file, to be compared against target file, is specified in
//    the source file spec ('infs' ). The version number for source file, to be
//    compared against target file, is specified in the file atom ( 'infa' ).
//
//    To compare files by date specify 'useSrcCrDateToCompare' within file atom
//    ( 'infa' ), and to compare files by version specify 'useVersProcToCompare'.
//
//    See the "File Compare by Procedure" example for instructions on how
//    to implement custom version comparison with the Installer.
//
//    NOTE: File versions and dates are ignored during Custom Remove.
