The parameters
${firstFile} and
${secondFile} specify the positions of the two compared files in
the command line for the external diff application. The parameter
${ancestorFile} specifies the common ancestor (that is, the BASE
revision of a file) in a three-way comparison. The working copy version of a file is
compared with the repository version, with the BASE revision (the latest revision read
from the repository by an Update or Synchronize operation) being the common ancestor of
these two compared versions.
Important: If the path to the external compare
application includes spaces (or any of the subsequent options or arguments), then each
of these paths or tokens must be double-quoted for the Syncro SVN Client to correctly parse and identify them. For example, C:\Program
Files\compareDir\app name.exe must be written as "C:\Program
Files\compareDir\app name.exe".
