+# BASTORD, a gemini server in bash

+
+# CONFIGURATION ################################################################
+# bastord has a few ways to set variables:
+#
+# - set environment variables
+# - use a config file (default: /etc/bastord.conf.sh)
+# - pass them in as arguments, Make-style
+#
+# Unless I can figure out how to tell bash to source a file and /not/ clobber
+# other environment variables, I can't just have the first two forms of setting
+# variables.  Basically, if you have a config file, use the make-style arguments
+# (bastord var=value).
