+# This script is called whenever you preview a file.
+# Its output is used as the preview.  ANSI color codes are supported.

+# NOTES: This script is considered a configuration file.  If you upgrade
+# ranger, it will be left untouched. (You must update it yourself)
+# NEVER make this script interactive. (by starting mplayer or something)

+# Meanings of exit codes:
+# code | meaning    | action of ranger
+# -----+------------+-------------------------------------------
+# 0    | success    | display stdout as preview
+# 1    | no preview | display no preview at all
+# 2    | plain text | display the plain content of the file
+# 3    | fix width  | success. Don't reload when width changes
+# 4    | fix height | success. Don't reload when height changes
+# 5    | fix both   | success. Don't ever reload
