/* PerforceSettings: Aggregates settings items and toplevel directory
 * which is determined externally by background checks and provides a convenience
 * for determining the common arguments.
 * Those must contain (apart from server connection settings) the working directory
 * with the "-d" option. This is because the p4 command line client detects its path
 * from the PWD environment variable which breaks relative paths since that is set by
 * the shell running Creator and is not necessarily that of the working directory
 * (see p4 documentation).
 * An additional complication is that the repository might be a symbolic link on Unix,
 * say "$HOME/dev" linked to "/depot". If the p4 client specification contains
 * "$HOME/dev", paths containing "/depot" will be refused as "not under client's view" by
 * p4. This is why the client root portion of working directory must be mapped for the
 * "-d" option, so that running p4 in "/depot/dev/foo" results in "-d $HOME/dev/foo". */
