@kha The runtime folder includes what is needed to link a standalone Lean program. It is still contains some unnecessary files. We will be able to remove them after we release Lean4.

\brief This is an auxiliary function used to simulate private declarations. Whenever we want to create a "private"
|
|
declaration, this module creates an internal "hidden" name that is not accessible to users.
|
|
In principle, users can access the internal names if they want by applying themselves the procedure used to create
|
|
the "hidden" names.
|
|
|
|
The optional \c base_hash can be used to influence the "hidden" name associated with \c n.
|
|
|
|
The mapping between \c n and the "hidden" name is saved in the .olean files.
