The mypear command sets up the path or paths in which Pyrus will look for installed packages. If multiple paths are specified, they should be separated by PATH_SEPARATOR, which is : on unix systems, and ; on Windows-based systems. If multiple paths are specified, only the first path will be used for installing packages. The other paths are only used to validate package dependencies.
mypear is a convenient alternative to using the set command to set the my_pear_path configuration variable.
