%description
Provides a local execution environment for testing and developing the
'FaaSr' workflows without requiring cloud infrastructure. The 'FaaSr'
package enables R developers to validate and test workflows locally before
deploying to Function-as-a-Service (FaaS) platforms. Key features include:
1) Parsing and validating JSON workflow configurations compliant with the
'FaaSr' schema 2) Simulated S3 storage operations using local file system
with local logging 3) Support for conditional branching 4) Support for
parallel rank functions execution 5) Workflow cycle detection and
validation 6) No cloud credentials or infrastructure required for testing
This package is designed for development and testing purposes. For
production deployment to cloud FaaS platforms, use the main 'FaaSr'
package available at <https://faasr.io/>.
