With this gem you can monitor Polish Post parcels and registered mail as well as packages shipped by Pocztex. It allows you to see basic data about the consignment as well as all the post offices it has gone through (including their locations and opening hours). The data is downloaded from a public SOAP API of the Polish Post (http://www.poczta-polska.pl/pliki/webservices/Metody%20i%20struktury%20uslugi%20sieciowej%20Poczty%20Polskiej%20SA.pdf) and wrapped into Ruby classes for your convenience.
