+Notice that the download site root location, e.g. [http://www.simantics.org/download/master/](http://www.simantics.org/download/master/) contains these same `.tpd` and `.target` files to\r
+enable sourcing both files directly from an HTTP URL.\r
+\r
+`.tpd` files can contain `include` statements that include other `.tpd` files from a URL.\r
+This greatly simplifies target definition by removing duplication from the their definitions. This is why \r
+publishing them online per platform branch is also highly useful.\r
+\r
+On the other hand legacy Buckminster builds can source `.target` files from a URL, which is why publishing them online\r
+per platform branch is useful.\r

+## Building .target files from the command line\r

+There is an example of how to do this with Maven at [build/pom.xml)(build/pom.xml).\r
+Essentially it sources the TPD tool and its required Eclipse parts from public P2\r
+repositories and uses `tycho-eclipserun-plugin` to run the *tpd converter application*\r
+to convert the `.tpd` file given as argument via `-Dtpd=tpd-path`.\r
