+this project is a tool CLI that can take CSV file and push its content into a sqlite database.
+
+the CSV files have the following columns:
+
+- Date
+- Eau
+- Scénic
+- Zoé
+
+the sqlite databases has been created with the following command:
+
+CREATE TABLE "eau"
+(
+date    TEXT not null
+primary key
+unique,
+releve  REAL not null,
+comment TEXT
+)
+
+CREATE TABLE "voiture1" (
+"date"	TEXT NOT NULL UNIQUE,
+"releve"	INTEGER NOT NULL,
+"comment"	TEXT,
+PRIMARY KEY("date")
+)
+
+CREATE TABLE "voiture2"
+(
+date    TEXT    not null,
+releve  INTEGER not null,
+comment TEXT
+)
+
+CSV columns "Date" and "Eau" has to be pushed to database table "eau" on columns "date" and "releve". no push if "Eau" is empty
+CSV columns "Date" and "Scénic" has to be pushed to database table "voiture1" on columns "date" and "releve". no push if "Scénic" is empty
+CSV columns "Date" and "Zoé" has to be pushed to database table "voiture2" on columns "date" and "releve". no push if "Zoé" is empty
+
+the CLI takes 2 parameters:
+
+- first is the name of the CSV file
+- second is the JDBC URL (for example, "jdbc:sqlite:/Users/kriss/NextCloud/Kriss/Dev/Perso/conso/db/conso.db")
+
+when launched, the tool checks that:
+
+- CSV file exists on the disk
+- CSV file contains exactly the described columns
+- Sqlite database is accessible through the JDBC URL
+- Ensure there won't be any duplicates inserted in the database (which means if the tool is launched twice in a row, no new lines will be inserted)
+- Tell the user how many new lines are going to be inserted in the database, and ask his agreement before proceeding
+- Performs the insert in the database
+
+this project is written in Rust.
