-# PROJECT NUMBER 1 - ALGORITHMS & PROGRAMATION I
-
-This folder contains the first project of "algoritmos y
-programacion I" a subject from Facultad de Ingenieria de la
-Universidad de Buenos Aires. The project is a program that
-runs on CLI which its function is to process data entered via
-a .csv file.
-
-What it does is receive a number for a country, date, and number of
-cases (of COVID19), and prints it on stdout with a human readable
-format.
-
-Bibliography:
-
-"The C programming language" - Brian W. Kernighan & Dennis Ritchie.
-
-NAME
- analisis_covid - analyze RAW data and export it with a human
- readable format.
-
-SYNOPSIS
- analisis_covid [-in] SOURCE [-out] DEST
- analisis_covid [-out] DEST [-in] SOURCE
-
-DESCRIPTION
- Process RAW data from a .csv(comma separated values) file,
- and export it to another .csv file, if the output file doesn't
- exist then it creates one with the specified name.
-
- When you invoke analisis_covid, expects.. to be continued
