This will be a collection of plugins/macros for the shaper module of salome.
To make the macros visible, they have to be registered in the addons_Features.xml, which can be found under the following path: ~/SALOME-9.15.0/BINARIES-CO7/SHAPER/share/salome/resources/shaper The file should look something like this:
<plugin>
<source path="../../../../bin/salome/macros/rectangle/widget.xml"/>
<source path="../../../../bin/salome/macros/compoundVertices/widget.xml"/>
<source path="../../../../bin/salome/macros/importParameters/widget.xml"/>
<source path="../../../../bin/salome/macros/midSurface/widget.xml"/>
<source path="../../../../bin/salome/macros/pipeNetwork/widget.xml"/>
</plugin>
