Simensen Rules
--------------

1 MUST immediately return the _file system path base_ if the _source_ is equal
  to the _logical path base_.

2 MUST return `false` if the _logical path base_ is not valid.

3 MUST append a directory to the _file system path base_, and

4 MUST replace the _logical path base_ in the _source_ with the _file system
  path base_, and

5 MUST replace _logical path separators_ in the _logical path suffix_ of the
  _source_ with directory separators, and

6 MUST return the transformed `source`


Braindead Rules
---------------

1 If the logical path prefix is not valid for the logical path, the
  implementation MUST abort the transformation and MAY return `false`.

2 The implementation MUST replace the logical path prefix in the logical path
  with the file system path prefix.

3 The implementation MUST replace logical path separators in the logical path
  suffix with directory separators.

4 The implementation MUST return the transformed string.


Analysis
--------

- simensen 2 and braindead 1 are the same
- simensen 4 and braindead 2 are the same
- simensen 5 and braindead 3 are the same
- simensen 6 and braindead 4 are the same
