 * then we have a new script, reproducible_info.sh which just outputs key-value pairs, like "ARCH=armhf", DATETIME="Mo 10. Aug 11:56:22 CEST 2015" and "TZ=UTC" and whatever.
-** this script is run on all nodes, but each run is triggered by a single job running on the main node (jenkins atm), so the results can be captured in /srv/reproducible-results/node-information/$NODE and then eg be used by reproducible_html_dashboard.sh to create the table with the differences between 1st and 2nd build...
+** this script is run on all nodes, via a for loop on the main node (jenkins atm), as part of dashboard.sh, and the results will be captured in /srv/reproducible-results/node-information/$NODE and then used by reproducible_html_dashboard.sh to create the table with the differences between 1st and 2nd build...
 *** document usage of -j 24/8/3 in write_explaination_table()
 ** /srv/reproducible-results/node-information/$NODE could also be read by reproducible_build.sh to determine the dpkg-architecture a node is captable of building, but I think we also want that info to be encoded in the build job names, so probably there's no need to read it...
