Optional -> Version check is optional, do it if version information
present but warn if it is missing.
Required -> Version check required; plugin must define a version
number and issue error message if it is missing.
majorVer: The required major version number. It is checked as follows:
< 0: major version numbers must be identical.
>= 0: is the lowest valid major version number allowed.
minorVer: The required minor version number, It is check as follows:
< 0: minor version numbers must be identical.

piSymbol: The plugin's object creator's unquoted function name. When this
symbol is looked-up, the defined version rule is applied.
Note: a plugin may not have a major.minor version number greater than the
program's major.minor version number unless either one is unreleased.
Unreleased versions can use any version. However, a message is issued.
