+python3-lazy_loader (Load subpackages and functions on demand)
+
+lazy_loader makes it easy to load subpackages and functions on demand.
+
+Motivation:
+1. Allow subpackages to be made visible to users without incurring
+import costs.
+2. Allow external libraries to be imported only when used, improving
+import times.

+# HOW TO EDIT THIS FILE:
+# The "handy ruler" below makes it easier to edit a package description.
+# Line up the first '|' above the ':' following the base package name, and
+# the '|' on the right side marks the last column you can put a character in.
+# You must make exactly 11 lines for the formatting to be correct.  It's also
+# customary to leave one space after the ':' except on otherwise blank lines.
