Learn English – Meaning & usage of “buy me cake”

The author of the free software CCleaner Enhancer wrote this in the changelog:

CCEnhancer has been updated for performance enhancements.

Previously; the tool would make a connection to the definition file, ensuring that the server is responding. This caused the annoying “hang” before the download commenced, as it would take several seconds for the domain resolution and connection to take place. The definition file would be almost fully (if not completely) downloaded before the connection was dropped. The new version connects to a much smaller file to validate the connection, eliminating this hang. The CCEnhancer icon has also been updated slightly, making it look better and reducing the size considerably.

Lastly, a “Buy Me Cake” button has been added which links directly to my paypal donate page.

So, quite simply, because the software is free, if you like it you can click the button and donate some money to say thank you, which the author can use to buy cake (or something else). The suggestion is to donate not a lot, but just enough for some cake.

It's similar to other donateware where the suggestion is to tip the author for a coffee, you may see "Buy me a cup of coffee" for other software.

Here's the French language file, which shows the corresponding texts used when it's used in French:

Buy Me Cake :)|Offre-moi un kouign-amann :)

A kouign-amann is a round, Breton cake.
