$ wget -O - -q -t 1 http[s]://[www.]server[.hu|.com|...]/[dir/]fermat.php?limit=1000 # LIMIT

$ wget -O - -q -t 1 http[s]://[www.]server[.hu|.com|...]/[dir/]soccer.php?save_file=writable/soccer.csv # SAVE_FILE - directory where the save file points to must be writable for the web-server

$ wget -O - -q -t 1 http[s]://[www.]server[.hu|.com|...]/[dir/]sunday.php?start_date=2019-1-10 # START_DATE

TODO and future consideration

Speed-up Fermat Equation module: currently it is suggested to run only up to limit 5000 to be done within normal time interval

Improve penalty handling of Soccer Championship Simulation: currently penalty results are not saved but the outcome is generated by random number generator

Also in Soccer Championship Simulation, improve tiebreakers handling: currently in Group stage / Tiebreakers rules 8. and 9. and the third-placed teams tiebreakers rules 5. are not implemented rather replaced by random number generation, source: https://en.wikipedia.org/wiki/UEFA_Euro_2020#Tiebreakers and https://en.wikipedia.org/wiki/UEFA_Euro_2020#Ranking_of_third-placed_teams

Also in Soccer Championship Simulation, parse and download inital data like rankings, groups directly from WIKI pages

Generate fancier output i.e. front-end and debug information

Add more error handling

Use spl_autoload_register() to load main class

Add unit test cases

Reduce accessing variables via $GLOBALS["VARIABLE_NAME"]

Isolate some program files not residing under web-space
