| -# IDLVersion is an object which stores the association of a given symbol
|
| -# name, with an AST node for a range of versions for that object.
|
| -#
|
| -# A vmin value of None indicates that the object begins at the earliest
|
| -# available version number. The value of vmin is always inclusive.
|
| -
|
| -# A vmax value of None indicates that the object is never deprecated, so
|
| -# it exists until it is overloaded or until the latest available version.
|
| -# The value of vmax is always exclusive, representing the first version
|
| -# on which the object is no longer valid.
