Why buy if source code is free?
PBaseUpload is written in Perl and being a strong supporter of Free Software, I have released the source code under GPL. While Perl is installed in almost all Linux installation, you will need to install it separately in Windows. Thus, in order to just run this script you will have to download and install a very large binary. Furthermore, the Perl script does not by itself provide the ‘Send to PBase’ right-click convenience. The PBaseUpload binary solves all these inconveniences. Please also note that official support is provided only to those who have bought the binary.
