4u'''Lazily import C{pygeodesy} modules and attributes, based on
5U{lazy_import<https://modutil.ReadTheDocs.io/en/latest/#lazy_import>}
6from I{Brett Cannon}'s U{modutil<https://PyPI.org/project/modutil>}.
8C{Lazy import} is I{supported only for }U{Python 3.7+
9<https://Snarky.Ca/lazy-importing-in-python-3-7>} and is I{enabled by
10default} in U{PyGeodesy 18.11.10<https://PyPI.org/project/PyGeodesy>}
11I{and newer}.
13To I{enable} C{lazy import}, set C{env} variable C{PYGEODESY_LAZY_IMPORT}
14to C{1}, C{2}, C{3} or higher prior to C{import pygeodesy}. To I{disable}
15C{lazy import}, set C{env} variable C{PYGEODESY_LAZY_IMPORT} to C{0} or
16an empty string. Use C{2} or higher to print a message for each lazily
17imported module and attribute, similar to C{env} variable C{PYTHONVERBOSE}
18showing imports. Using C{3} or higher also shows the importing file name
19and line number.
21@note: C{Lazy import} applies only to top-level modules of C{pygeodesy}.
22 The C{lazy import} of a top-level module invariably loads all
23 sub-modules imported by that top-level module.
25@note: C{Lazy import} raises a L{LazyAttributeError} or L{LazyImportError}
26 depending on the cause of the error and such errors can occur late,
27 after all initial imports.
