-ptipath

Specifies an additional search directory for template source.

This option is an alternative to the normal search path set by -Ipathname. If the -ptipath option is used, the compiler looks for template definition files on this path and ignores the -Ipathname option.

Using the -Ipathname option instead of -ptipath produces less confusion.
