+               <description>&lt;p&gt;A few days, I rescued a Windows victim over to Debian.  To try to
+rescue the remains, I helped set up automatic sync with Google Drive.
+I did not find any sensible Debian package handling this
+automatically, so I rebuild the grive2 source from
+&lt;a href=&quot;http://www.webupd8.org/&quot;&gt;the Ubuntu UPD8 PPA&lt;/a&gt; to do the
+task and added a autostart desktop entry and a small shell script to
+run in the background while the user is logged in to do the sync.
+Here is a sketch of the setup for future reference.&lt;/p&gt;
+
+&lt;p&gt;I first created &lt;tt&gt;~/googledrive&lt;/tt&gt;, entered the directory and
+ran &#39;&lt;tt&gt;grive -a&lt;/tt&gt;&#39; to authenticate the machine/user.  Next, I
+created a autostart hook in &lt;tt&gt;~/.config/autostart/grive.desktop&lt;/tt&gt;
+to start the sync when the user log in:&lt;/p&gt;
+
+&lt;p&gt;&lt;blockquote&gt;&lt;pre&gt;
+[Desktop Entry]
+Name=Google drive autosync
+Type=Application
+Exec=/home/user/bin/grive-sync
+&lt;/pre&gt;&lt;/blockquote&gt;&lt;/p&gt;
+
+&lt;p&gt;Finally, I wrote the &lt;tt&gt;~/bin/grive-sync&lt;/tt&gt; script to sync
+~/googledrive/ with the files in Google Drive.&lt;/p&gt;
+
+&lt;p&gt;&lt;blockquote&gt;&lt;pre&gt;
+#!/bin/sh
+set -e
+cd ~/
+cleanup() {
+    if [ &quot;$syncpid&quot; ] ; then
+        kill $syncpid
+    fi
+}
+trap cleanup EXIT INT QUIT
+/usr/lib/grive/grive-sync.sh listen googledrive 2&gt;&amp;1 | sed &quot;s%^%$0:%&quot; &amp;
+syncpdi=$!
+while true; do
+    if ! xhost &gt;/dev/null 2&gt;&amp;1 ; then
+        echo &quot;no DISPLAY, exiting as the user probably logged out&quot;
+        exit 1
+    fi
+    if [ ! -e /run/user/1000/grive-sync.sh_googledrive ] ; then
+        /usr/lib/grive/grive-sync.sh sync googledrive
+    fi
+    sleep 300
+done 2&gt;&amp;1 | sed &quot;s%^%$0:%&quot;
+&lt;/pre&gt;&lt;/blockquote&gt;&lt;/p&gt;
+
+&lt;p&gt;Feel free to use the setup if you want.  It can be assumed to be
+GNU GPL v2 licensed (or any later version, at your leisure), but I
+doubt this code is possible to claim copyright on.&lt;/p&gt;

-               <description>&lt;p&gt;Five years ago,
-&lt;a href=&quot;http://people.skolelinux.org/pere/blog/What_is_the_most_supported_MIME_type_in_Debian_.html&quot;&gt;I
-measured what the most supported MIME type in Debian was&lt;/a&gt;, by
-analysing the desktop files in all packages in the archive.  Since
-then, the DEP-11 AppStream system has been put into production, making
-the task a lot easier.  This made me want to repeat the measurement,
-to see how much things changed.  Here are the new numbers, for
-unstable only this time:
-
-&lt;p&gt;&lt;strong&gt;Debian Unstable:&lt;/strong&gt;&lt;/p&gt;
-
-&lt;pre&gt;
-  count MIME type
-  ----- -----------------------
-     56 image/jpeg
-     55 image/png
-     49 image/tiff
-     48 image/gif
-     39 image/bmp
-     38 text/plain
-     37 audio/mpeg
-     34 application/ogg
-     33 audio/x-flac
-     32 audio/x-mp3
-     30 audio/x-wav
-     30 audio/x-vorbis+ogg
-     29 image/x-portable-pixmap
-     27 inode/directory
-     27 image/x-portable-bitmap
-     27 audio/x-mpeg
-     26 application/x-ogg
-     25 audio/x-mpegurl
-     25 audio/ogg
-     24 text/html
-&lt;/pre&gt;
-
-&lt;p&gt;The list was created like this using a sid chroot: &quot;cat
-/var/lib/apt/lists/*sid*_dep11_Components-amd64.yml.gz| zcat | awk &#39;/^
-- \S+\/\S+$/ {print $2 }&#39; | sort | uniq -c | sort -nr | head -20&quot;&lt;/p&gt;
-
-&lt;p&gt;It is interesting to see how image formats have passed text/plain
-as the most announced supported MIME type.  These days, thanks to the
-AppStream system, if you run into a file format you do not know, and
-want to figure out which packages support the format, you can find the
-MIME type of the file using &quot;file --mime &amp;lt;filename&amp;gt;&quot;, and then
-look up all packages announcing support for this format in their
-AppStream metadata (XML or .desktop file) using &quot;appstreamcli
-what-provides mimetype &amp;lt;mime-type&amp;gt;.  For example if you, like
-me, want to know which packages support inode/directory, you can get a
-list like this:&lt;/p&gt;
-
-&lt;p&gt;&lt;blockquote&gt;&lt;pre&gt;
-% appstreamcli what-provides mimetype inode/directory | grep Package: | sort
-Package: anjuta
-Package: audacious
-Package: baobab
-Package: cervisia
-Package: chirp
-Package: dolphin
-Package: doublecmd-common
-Package: easytag
-Package: enlightenment
-Package: ephoto
-Package: filelight
-Package: gwenview
-Package: k4dirstat
-Package: kaffeine
-Package: kdesvn
-Package: kid3
-Package: kid3-qt
-Package: nautilus
-Package: nemo
-Package: pcmanfm
-Package: pcmanfm-qt
-Package: qweborf
-Package: ranger
-Package: sirikali
-Package: spacefm
-Package: spacefm
-Package: vifm
-%
-&lt;/pre&gt;&lt;/blockquote&gt;&lt;/p&gt;
-
-&lt;p&gt;Using the same method, I can quickly discover that the Sketchup file
-format is not yet supported by any package in Debian:&lt;/p&gt;
-
-&lt;p&gt;&lt;blockquote&gt;&lt;pre&gt;
-% appstreamcli what-provides mimetype  application/vnd.sketchup.skp
-Could not find component providing &#39;mimetype::application/vnd.sketchup.skp&#39;.
-%
-&lt;/pre&gt;&lt;/blockquote&gt;&lt;/p&gt;
-
-&lt;p&gt;Yesterday I used it to figure out which packages support the STL 3D
-format:&lt;/p&gt;
-
-&lt;p&gt;&lt;blockquote&gt;&lt;pre&gt;
-% appstreamcli what-provides mimetype  application/sla|grep Package
-Package: cura
-Package: meshlab
-Package: printrun
-%
-&lt;/pre&gt;&lt;/blockquote&gt;&lt;/p&gt;
-
-&lt;p&gt;PS: A new version of Cura was uploaded to Debian yesterday.&lt;/p&gt;
