+ <description><p>The chrpath package provide a simple command line tool to remove
+the rpath or runpath of compiled ELF program. It is almost 10 years
+since I updated the code base, but I stumbled over the tool today, and
+decided it was time to move the code base from Subversion to git and
+find a new home for it, as the previous one (Debian Alioth) has been
+shut down. I decided to go with
+<a href="https://codeberg.org/">Codeberg</a> this time, as it is my git
+service of choice these days, did a quick and dirty migration to git
+and updated the code with a few patches I found in the Debian bug
+tracker. These are the release notes:</p>
+
+<p>New in 0.17 released 2023-11-10:</p>
+
+<ul>
+<li>Moved project to Codeberg, as Alioth is shut down.</li>
+<li>Add Solaris support (use &lt;sys/byteorder.h> instead of &lt;byteswap.h>).
+ Patch from Rainer Orth.</li>
+<li>Added missing newline from printf() line. Patch from Frank Dana.</li>
+<li>Corrected handling of multiple ELF sections. Patch from Frank Dana.</li>
+<li>Updated build rules for .deb. Partly based on patch from djcj.</li>
+</ul>
+
+<p>The latest edition is tagged and available from
+<a href="https://codeberg.org/pere/chrpath">https://codeberg.org/pere/chrpath</a>.

- <description><p>Today I finally found time to track down a useful radio frequency
-scanner for my software defined radio. Just for fun I tried to locate
-the radios used in the areas, and a good start would be to scan all
-the frequencies to see what is in use. I've tried to find a useful
-program earlier, but ran out of time before I managed to find a useful
-tool. This time I was more successful, and after a few false leads I
-found a description of
-<a href="https://www.kali.org/tools/rtlsdr-scanner/">rtlsdr-scanner
-over at the Kali site</a>, and was able to track down
-<a href="https://gitlab.com/kalilinux/packages/rtlsdr-scanner.git">the
-Kali package git repository</a> to build a deb package for the
-scanner. Sadly the package is missing from the Debian project itself,
-at least in Debian Bullseye. Two runtime dependencies,
-<a href="https://gitlab.com/kalilinux/packages/python-visvis.git">python-visvis</a>
-and
-<a href="https://gitlab.com/kalilinux/packages/python-rtlsdr.git">python-rtlsdr</a>
-had to be built and installed separately. Luckily '<tt>gbp
-buildpackage</tt>' handled them just fine and no further packages had
-to be manually built. The end result worked out of the box after
-installation.</p>
-
-<p>My initial scans for FM channels worked just fine, so I knew the
-scanner was functioning. But when I tried to scan every frequency
-from 100 to 1000 MHz, the program stopped unexpectedly near the
-completion. After some debugging I discovered USB software radio I
-used rejected frequencies above 948 MHz, triggering a unreported
-exception breaking the scan. Changing the scan to end at 957 worked
-better. I similarly found the lower limit to be around 15, and ended
-up with the following full scan:</p>

-
-<p>Saving the scan did not work, but exporting it as a CSV file worked
-just fine. I ended up with around 477k CVS lines with dB level for
-the given frequency.</p>
-
-<p>The save failure seem to be a missing UTF-8 encoding issue in the
-python code. Will see if I can find time to send a patch
-<a href="https://github.com/CdeMills/RTLSDR-Scanner/">upstream</a>
-later to fix this exception:</p>
