NOTE: the website is currently near its capacity limit. Some operations (uploads, downloads) may be intermittently unavailable while I work on the problem. Please be patient, hopefully this will be fixed soon (March 16, 2024).

Update February 23, 2025: My ISP regularly makes changes to the setup of this VPS, which causes some parts of the entirety of the manuals pages to break, as it did for the last week or two.

I apologize for that. At the moment, it is repaired... Hold your breath.
