NAME

zoryn-gen-opam2spec - Generate spec file from opam.

SYNOPSIS

zoryn gen opam2spec [OPTION]… [OPAM-FILE]

DESCRIPTION

Generate RPM spec file from opam file. Can work with local opam files or clone package from opam repository.

Supports single-package and multi-package opam projects. For multi-package projects, creates combined spec with all subpackages.

Generated spec includes BuildRequires from opam dependencies (checking RDB for existing packages), proper License from opam metadata, and %check section for packages with tests.

Also generates .gear/rules file with appropriate tar and spec directives, and detects tag prefix from upstream git.

With --sync, compares existing spec file BuildRequires with opam dependencies and shows what needs to be added or removed.
