 ToolJet is an open-source low-code framework to build and deploy internal tools quickly without much effort from the engineering teams. You can connect to your data sources, such as databases (like PostgreSQL, MongoDB, Elasticsearch, etc), API endpoints (ToolJet supports importing OpenAPI spec & OAuth2 authorization), and external services (like Stripe, Slack, Google Sheets, Airtable) and use our pre-built UI widgets to build internal tools.

-### ynh_script_progression will show to your final users the progression of each scripts.
-### In order to do that, --weight will represent the relative time of execution compared to the other steps in the script.
-### --time is a packager option, it will show you the execution time since the previous call.
-### This option should be removed before releasing your app.
-### Use the execution time, given by --time, to estimate the weight of a step.
-### A common way to do it is to set a weight equal to the execution time in second +1.
-### The execution time is given for the duration since the previous call. So the weight should be applied to this previous call.
