+###############################################################
+#
+# Uses fzf to provide a selection list for tmuxinator projects.
+#
+# Overview:
+#
+# tmuxinator-fzf-start.sh will open fzf with a multi select
+# list of tmuxinator projects.  Upon selecting project/s each
+# project will have `tmuxinator start` run, and when complete
+# tmux will be attached, or if tmux is already running, a
+# session selection interface will be provided.
+#
+# If an initial query is provided, and only one match results,
+# the project will be automatically opened without user input.
+#
+# Usage:
+#
+# tmuxinator-fzf-start.sh
+# tmuxinator-fzf-start.sh "Query"
+#
+# Expectations:
+#
+# - tmuxinator is on $PATH
+# - fzf is on $PATH
+# - tmux is on $PATH
+
+# Allow the user to select projects via fzf
