# License file

The Editran/SEPA program requires a license file called `licencia.dat`, which must be located in the SEPA root folder.

This file must be requested from Editran Support by indicating the hostid and the operating system of the machine. There are two ways to obtain this information:

* By running the file `checkLic.bat`/`checkLic.sh` found in the folder `SEPA/scripts` of your operating system. When this file is run from the same folder where it is located, the result of the license check will be returned on screen.

If you try to run the Editran/SEPA program without a license, the program will fail due to an incorrect license, leaving the hostid and the machine's operating system in the log.

# Agent Instructions

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation by asking a question.

Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters:

```
GET https://docs.editran.onesait.com/documentacion-editran/documentacion-editran-editran-sepa-v3-open-en/requisitos-e-instalacion/fichero-de-licencia.md?ask=<question>&goal=<user_goal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
