The custom shape code is designed so that a sheet of objects can be self contained in a single directory. Installing new shapes can be as easy as untaring a .tar.gz file to ~/.dia/shapes or $(prefix)/share/dia/shapes, with the sheet description going to ~/.dia/sheets

If you have any suggestions for this code, please tell me.
