Reliable official narrative history is thin, so this enrichment keeps the history to the GNU identity, source hosting, and package-manager role. ### Adoption history The input package facts show cflow packaged in Homebrew, Alpine, Debian/Ubuntu, Fedora, MacPorts, Nix, openSUSE, and other Unix-like package ecosystems. ### How it is used cflow is used by C programmers and maintainers to inspect function relationships and call graphs from source trees, usually as a command-line aid during code reading or static analysis. ### Why package nerds care GNU cflow is a classic small GNU utility: old-school source inspection, text output, manual pages, init files, and broad distro packaging without a large service footprint. ### Timeline - GNU project: cflow is maintained as GNU software. - Savannah era: official source repository hosted on git.savannah.gnu.org. - Current packaging: input facts show broad availability across Unix package managers. ### Related projects - GNU cflow sits near other source-reading and static-analysis command-line tools rather than compilers or language servers. ### Sources - - - - - ## Security Notes narrow executable package without higher-risk signals. - **Geiger risk:** green / low - narrow executable package without higher-risk signals ## Configuration and credential file locations These source-backed paths show where this package keeps local settings or durable credentials. Automic Vault can use them as review targets for secret scanning, migration, and command approval. ## Configuration files - Unix: ~/.cflow.d/*.cfo, ~/.cflow.d/default.cfo, /usr/share/cflow/site-init/*.cfo, /usr/share/cflow/site-init/1.8/*.cfo, /usr/local/share/cflow/site-init/*.cfo, /usr/local/share/cflow/site-init/1.8/*.cfo, $CFLOWRC, ~/.cflowrc ## Source Database Details -
