flatpak-builder:tldr:5a1a4

The command flatpak-builder is used to build a Flatpak application from source code and generate a Flatpak repository. Here is how each part of the command is explained:

• flatpak-builder: This is the command-line tool provided by Flatpak for building applications.
• --repo=${repository_name}: This option specifies the name of the repository where the built application will be stored. ${repository_name} needs to be replaced with the actual name of the repository.
• ${path-to-build_directory}: This is the path to the directory where the build process will take place. It is usually an empty directory where the required dependencies and build artifacts will be stored.
• ${path-to-manifest}: This is the path to the manifest file of the Flatpak application. The manifest file contains metadata, build instructions, and dependencies of the application. It is usually a YAML file with a .yaml or .yml extension.

In summary, this command instructs flatpak-builder to build an application using the specified manifest file and place the resulting built application in the repository with the given name.
