(** PPX and Syntax Preprocessor Resolution
This module handles the resolution of PPX preprocessors and syntax extensions
(like camlp4) for OCaml compilation targets.
= Key Responsibilities =
- Resolve camlp4/syntax preprocessor dependencies
- Generate preprocessor flags for compilation
- Handle both internal and external syntax packages
- Support camlp4o and camlp4r syntax variants
= Historical Context =
OCaml has evolved through several preprocessing systems:
- camlp4: Original extensible preprocessor (OCaml < 4.08)
- PPX: Modern preprocessor system using AST transformations
- This module supports both for compatibility
