+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 de relevé de l'index
+- Type d'index
+- Index Heures pleines (kWh)
+- Index Heures creuses (kWh)
+
+the sqlite database has been created with the following command:
+
+CREATE TABLE "electricite" (
+"date"	TEXT NOT NULL UNIQUE,
+"releveHC"	INTEGER NOT NULL,
+"releveHP"	INTEGER NOT NULL,
+"comment"	TEXT,
+PRIMARY KEY("date")
+)
+
+CSV column "Date de relevé de l'index" has to be mapped with database column "date"
+CSV column "Index Heures pleines (kWh)" has to be mapped with database column "releveHP"
+CSV column "Index Heures creuses (kWh)" has to be mapped with database column "releveHC"
+
+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.
