## What it is
Fortran Package Manager (fpm) is a package manager and build system for Fortran, with a user interface modeled after Rust's Cargo. It simplifies building Fortran programs and libraries, running tests and examples, and distributing packages as dependencies via local or online registries.

## Use cases
- build a fortran project
- manage fortran package dependencies
- create a new fortran project scaffold
- run fortran tests and examples
- publish a fortran library to a registry
- configure build profiles and compiler flags for fortran

## When to choose
- you are starting a new Fortran project and want a modern Cargo-like workflow
- you want simple dependency management and a package registry for Fortran
- you need cross-platform builds of Fortran code without writing Makefiles

## When to avoid
- you have a large legacy Fortran codebase with complex existing build systems like CMake
- you need features beyond fpm's current prototype-stage capabilities
- you are not working with Fortran (this is unrelated to Jordan Sissel's fpm)

## Facets
- artifact type: cli-tool
- maturity: active
- function: package-manager, build-tool, cli, developer-tools
- domain: developer-tools, programming-languages
- platform: windows, cli, cross-platform
- tags: fortran, cargo-inspired, dependency-management, build-system, fpm-registry, command-line, linux, macos
