CMHG/CMunge configuration knowledge is scattered; this skill consolidates essential CMHG directives and their usage for reliable RISC OS module development.
Create a CMHG header for a new RISC OS module using CMunge directives described in this skill.

CMHG files use directives like title-string, help-string, and initialisation-code to define RISC OS module components. Apply CMunge syntax to generate the required headers and veneers for ROM or loadable modules.
CMHG vector directives define vector-traps to intercept system vectors in RISC OS modules. They generate veneer code allowing your module to hook into OS functionality safely.
Use CMunge when creating headers for ROM or loadable modules requiring standard entry points. It processes CMHG files to generate C headers and assembly veneers for module initialization.
The title-string directive defines the module's internal registered OS name, while the help-string provides user-facing text displayed by the OS help system. Both are required in CMHG configuration.
CMunge supports debugging initialisation-code directives by generating veneers allowing module initialization routines to return errors properly. Reference documentation clarifies syntax for error handling and startup.
CMHG headers fail to generate when directive syntax is malformed or required directives like title-string are missing. Verify your CMHG file structure against directive references and ensure proper formatting.
