RPM packages\n- ... add yours!\n\n## Features\n\nIf resolvo is unable to find a solution it outputs a human-readable error message:\n\n```\nThe following packages are incompatible\n├─ bluesky-widgets \u003e=0, \u003c100 can be installed with any of the following options:\n│  └─ bluesky-widgets 42 would require\n│     └─ suitcase-utils \u003e=0, \u003c54, which can be installed with any of the following options:\n│        └─ suitcase-utils 53\n└─ suitcase-utils \u003e=54, \u003c100 cannot be installed because there are no viable options:\n   └─ suitcase-utils 54, which conflicts with the versions reported above.\n```\n\nResolve provides a generic interface which allows integrating the solver with a variety of package managers. For instance resolvo is used in [rattler](https://github.com/mamba-org/rattler) and [pixi](https://github.com/prefix-dev/pixi) to solve packages from the conda ecosystem.\n\nOriginally resolvo started out as a port/fork of [libsolv](https://github.com/openSUSE/libsolv) but it has since then diverged substantially. However, the same CDCL algorithm based on MiniSats [An Extensible SAT-solver](http://minisat.se/downloads/MiniSat.pdf) is still used underneath. Major differences compared to libsolv are:\n\n* Resolvo does not come with built-in support for several packaging ecosystems but instead provides a generic interface to allow it to be used in different scenarios.\n* Resolvo has support for incremental/lazy solving. This allows users to quickly find solutions in ecosystems where retrieving package metadata is expensive.\n* Resolvo is considerably faster than libsolv in large complex cases.\n* Resolvo can easily be used in multithreaded environments.\n* Resolvo provides human-readable error messages out-of-the-box.\n* Resolvo optionally provides an async interface to allow concurrent metadata fetching.\n* However, Libsolv is more extensive and supports more complex queries.\n\n## Contributing 😍\n\nWe would love to have you contribute! \nSee the CONTRIBUTION.md for more info.
