You can add custom scripts to this directory and declare them to be run at build time in the scripts: section of recipe.yml. Custom scripts can be run at either the pre: execution phase right after the custom repositories are added, or at the post: phase after all of the automatic build steps.

Your scripts will be given exactly one argument when they are executed, which specifies its precise execution phase (pre or post). The primary purpose of this argument is to streamline the reuse of scripts for multiple stages.

`autorun.sh`

autorun.sh is enabled by default and automatically runs all scripts in the folders scripts/pre/ and scripts/post/ at the correct execution phases.
