# Provs-core
the core engine of the provs framework.
## Provs framework
Framework for automating shell- and other system-tasks for provisioning reasons or other purposes.
Can easily be run
* locally
* remotely
* in a docker container
* or with any self-defined custom processor
Combines the
* convenience and robustness of a modern programming language (Kotlin) with
* power of being able to use shell commands and with
* clear and detailed result summary of the built-in failure handling.
## Provs-core
Provs-core provides the core component with
* execution engine
* failure handling
* multiple execution processors
* execution summary and logging
* support for secrets
## Usage
### Run hello world
Locally:
`kotlinc -cp build/libs/provs-latest.jar -script scripts/HelloWorldLocal.kts`
Remotely:
`kotlinc -cp build/libs/provs-latest.jar -script scripts/HelloWorldRemote.kts`
### Other examples
For a bunch of usage examples please have a look at provs-ubuntu-extensions.
