Announcement text given by the package's contributor:
----------------------------------------------------------------------
This package targets the simple problem of producing block diagrams
and bond graphs.  In more detail, the provided functionality can be
divided into
o  Standard elements such as labeled blocks and bond graph arrows.
o  Standardized way for selecting input and output points on blocks.
o  Means for the construction of "carpented" paths connecting points.
o  Standardized label positioning along block connections.
o  Higher-level macros that specialize and/or combine some of the above.

An important example from the group of higher-level macros is the 
macro that takes two blocks as arguments and generates a path connecting
them.
