This directory contains code derived from the `lp_solve` project,
internalized in `QCA` for package-internal use.

Provenance

- Original solver project: https://lp-solve.github.io/
- R wrapper package used as the import base: `lpSolve`

License

- Upstream `lpSolve` declares `License: LGPL-2` in its `DESCRIPTION`.
- The code in this directory should therefore be treated as third-party
  code under LGPL-2, as imported from that source.

Local modifications

- The imported code has been substantially pruned and modified for the
  internal needs of `QCA`.
- In particular, package-interface code, parser/file I/O code, and
  multiple generic reporting and solver subsystems were reduced or
  replaced with compatibility stubs.

Notes

- This file is a local provenance notice added by `QCA`.
- It does not replace any upstream copyright or license statements that
  may exist in individual source files.
