+# Provide a simple shell extension to save and load govc
+# environments to disk. No more running `export GOVC_ABC=xyz`
+# in different shells over and over again. Loading the right
+# govc environment variables is now only one short and
+# autocompleted command away!
+#
+# Usage:
+# * Source this file from your `~/.bashrc` or running shell.
+# * Execute `govc-env` to print GOVC_* variables.
+# * Execute `govc-env --save <name>` to save GOVC_* variables.
+# * Execute `govc-env <name>` to load GOVC_* variables.
