rederr is a small tool that invokes another command and propagates its stdout as-is and its stderr in ANSI red.
Just prefix any command line of your choice with rederr and it will make it easy for to figure out what is error and what is output.
Example:
First ensure you have the meson and ninja binaries installed, as well as the
required C compiler (gcc) and related tools.
Run meson build in the project root directory.
Next change into the build directory with cd build/
Finally run ninja in that directory.
You should now have a rederr binary which you can copy to your $PATH.
Example:
