- First bello package
- Example second item in the changelog for version-release 0.1-1

The BuildRequires directive, which specifies build-time dependencies for the package, was deleted because there is no building step for bello. Bash is a raw interpreted programming language, and the files are just installed to their location on the system.

The Requires directive, which specifies run-time dependencies for the package, include only bash, because the bello script requires only the bash shell environment to execute.

The %build section, which specifies how to build the software, is blank, because a bash does not need to be built.

For installing bello you only need to create the destination directory and install the executable bash script file there. Hence, you can use the install command in the %install section. RPM macros allow to do this without hardcoding paths.
