+/* ERROR/WARNING messages:
+
+E: Python support missing! Compile with PYTHON package installed!
+
+UNDOCUMENTED
+
+U: Invalid python command
+
+Self-explanatory.  Check the input script syntax and compare to the
+documentation for the command.  You can use -echo screen as a
+command-line option when running LAMMPS to see the offending line.
+
+U: Python invoke of undefined function
+
+Cannot invoke a function that has not been previously defined.
+
+U: Python variable does not match Python function
+
+This matching is defined by the python-style variable and the python
+command.
+
+U: Cannot embed Python when also extending Python with LAMMPS
+
+When running LAMMPS via Python through the LAMMPS library interface
+you cannot also user the input script python command.
+
+U: Could not initialize embedded Python
+
+The main module in Python was not accessible.
+
+U: Could not open Python file
+
+The specified file of Python code cannot be opened.  Check that the
+path and name are correct.
+
+U: Could not process Python file
+
+The Python code in the specified file was not run successfully by
+Python, probably due to errors in the Python code.
+
+U: Could not process Python string
+
+The Python code in the here string was not run successfully by Python,
+probably due to errors in the Python code.
+
+U: Could not find Python function
+
+The provided Python code was run successfully, but it not
+define a callable function with the required name.
+
+U: Python function is not callable
+
+The provided Python code was run successfully, but it not
+define a callable function with the required name.
+
+U: Could not create Python function arguments
+
+This is an internal Python error, possibly because the number
+of inputs to the function is too large.
+
+U: Could not evaluate Python function input variable
+
+Self-explanatory.
+
+U: Python function evaluation failed
+
+The Python function did not run successfully and/or did not return a
+value (if it is supposed to return a value).  This is probably due to
+some error condition in the function.
