 The **PathMap** compiler option specifies how to map physical paths to source path names output by the compiler. This option maps each physical path on the machine where the compiler runs to a corresponding path that should be written in the output files. In the following example, `path1` is the full path to the source files in the current environment, and `sourcePath1` is the source path substituted for `path1` in any output files. To specify multiple mapped source paths, separate each with a comma.
