+<h1>PSPP autobuilder</h1>
+<p>
+ The PSPP autobuilder runs each time a developer makes a change.
+ Directories are named by the time that the build occurred,
+ in <code>YYYYMMDDhhmmss</code> form. Each directory contains one
+ build, with the following subdirectories:
+</p>
+
+<ul>
+ <li><code>source</code>: Source build. Also includes user and
+ developer manual builds.</li>
+
+ <li><code>x86_64</code>: x86-64 GNU/Linux binaries. The binary
+ tarball is "relocatable": it is usable extracted into any
+ directory location.</li>
+
+ <li><code>flatpak</code>: Flatpak binary data. You can install it
+ with <code>flatpak install</code> followed by the URL of
+ the <code>.flatpakref</code> file also in the directory.</li>
+</ul>
+
+<p>
+ This directory also supplies the following redirects for the latest
+ versions of various build products:
+</p>
+
+<ul>
+ <li><a href="latest">latest</a> for the most recent build
+ directory</li>
+
+ <li><a href="latest-source.tar.gz">latest-source.tar.gz</a> for the
+ latest source build tarball.</li>
+
+ <li><a href="latest-x86_64.tar.gz">latest-x86_64.tar.gz</a> for the
+ latest x86-64 binary tarball.</li>
+
+ <li><a href="latest-org.gnu.pspp.flatpakref">latest-org.gnu.pspp.flatpakref</a>
+ for the latest Flatpak binary.</li>
+
+ <li><a href="latest-windows">latest-windows</a> to
+ the <a href="https://caeis.etech.fh-augsburg.de/downloads/windows/pspp-win-daily">Windows
+ daily build</a> for the most recent build. These builds use the
+ autobuilder products from here, so the latest build here, if it is
+ recent, might not yet have a Windows build.</li>
+</ul>
+
+<p>
+ Builds can fail, so sometimes the above might be broken. You are
+ welcome to report this kind of brokenness, or PSPP bugs in general,
+ to <a href="mailto:bug-gnu-pspp@gnu.org">bug-gnu-pspp@gnu.org</a>.
