Réécriture pour remplacer l'utilisation d'une base sqlite par des tables de hachage, ce qui augmente drastiquement les performances.
Modification de la sortie des logs pour être un peu plus homogène et donc facile à parser dans graylog.

 ## Getting started
 
-To make it easy for you to get started with GitLab, here's a list of recommended next steps.
+Le programme parselog-ldap permet de construire des logs LDAP lisibles et exploitables. Il doit se lancer sur le serveur LDAP. Il ne peut pas recevoir les logs de plusieurs serveurs LDAP car il pourrait y avoir plusieurs fois le même numéro de connexion et donc des logs inconsistants.

-# Editing this README
-
-When you're ready to make this README your own, just edit this file and use the handy template below (or feel free to structure it however you want - this is just a starting point!). Thank you to [makeareadme.com](https://www.makeareadme.com/) for this template.
-
-## Suggestions for a good README
-Every project is different, so consider which of these sections apply to yours. The sections used in the template are suggestions for most open source projects. Also keep in mind that while a README can be too long and detailed, too long is better than too short. If you think your README is too long, consider utilizing another form of documentation rather than cutting out information.
-
-## Name
-Choose a self-explaining name for your project.
-
-## Description
-Let people know what your project can do specifically. Provide context and add a link to any reference visitors might be unfamiliar with. A list of Features or a Background subsection can also be added here. If there are alternatives to your project, this is a good place to list differentiating factors.
-
-## Badges
-On some READMEs, you may see small images that convey metadata, such as whether or not all the tests are passing for the project. You can use Shields to add some to your README. Many services also have instructions for adding a badge.
-
-## Visuals
-Depending on what you are making, it can be a good idea to include screenshots or even a video (you'll frequently see GIFs rather than actual videos). Tools like ttygif can help, but check out Asciinema for a more sophisticated method.
-
-## Installation
-Within a particular ecosystem, there may be a common way of installing things, such as using Yarn, NuGet, or Homebrew. However, consider the possibility that whoever is reading your README is a novice and would like more guidance. Listing specific steps helps remove ambiguity and gets people to using your project as quickly as possible. If it only runs in a specific context like a particular programming language version or operating system or has dependencies that have to be installed manually, also add a Requirements subsection.
-
-## Usage
-Use examples liberally, and show the expected output if you can. It's helpful to have inline the smallest example of usage that you can demonstrate, while providing links to more sophisticated examples if they are too long to reasonably include in the README.
+Il faudra ensuite indiquer au rsyslog du serveur LDAP d'envoyer les logs LDAP sur le démon, c'est à dire s'il écoute sur le port 8080 d'envoyer en TCP sur 127.0.0.1:8080. Celui-ci va en retour envoyer les logs sur le loghost indiqué en utilisant le protocole TCP. 
 
-## Support
-Tell people where they can go to for help. It can be any combination of an issue tracker, a chat room, an email address, etc.
+Le démon parselog-ldap ne doit pas tourner en tant que root, il faut donc lui créer un utilisateur sous lequel il sera exécuté. 
 
-## Roadmap
-If you have ideas for releases in the future, it is a good idea to list them in the README.
+## Compilation
 
-## Contributing
-State if you are open to contributions and what your requirements are for accepting them.
+Installer [rust](https://www.rust-lang.org/tools/install) puis: ```cargo build -r```
 
-For people who want to make changes to your project, it's helpful to have some documentation on how to get started. Perhaps there is a script that they should run or some environment variables that they need to set. Make these steps explicit. These instructions could also be useful to your future self.
+Le binaire sera présent dans target/release
 
-You can also document commands to lint the code or run tests. These steps help to ensure high code quality and reduce the likelihood that the changes inadvertently break something. Having instructions for running tests is especially helpful if it requires external setup, such as starting a Selenium server for testing in a browser.
+## Fonctionnement
 
-## Authors and acknowledgment
-Show your appreciation to those who have contributed to the project.
+A la réception d'un log une première expression régulière va analyser la commande LDAP (BIND, ADD, DEL, SRCH...) et va envoyer le log dans la fonction adequat. Les logs sont construit en récupérant les info dans les logs et en utilisant le numéro de connexion et numéro d'opération. Tout est stocké dans des tables de hashage gérés dans le fichier hashmap.rs. Quand on tombe sur la commande RESULT, on va aller récupérer les infos préalablement stocké, construile la ligne de log à envoyer, l'envoyer avec la fonction sendlog() et nettoyer les tables de hashage.
 
 ## License
-For open source projects, say how it is licensed.

 ## Project status
 If you have run out of energy or time for your project, put a note at the top of the README saying that development has slowed down or stopped completely. Someone may choose to fork your project or volunteer to step in as a maintainer or owner, allowing your project to keep going. You can also make an explicit request for maintainers.
