+# #############################################################################
+# nlay: a customizable script to play files in different apps by file type
+#
+# usage: nlay file type
+#
+# MUST READ:
+#
+# 1. Feel free to change the default apps to your favourite ones.
+#    Simple use 'run_fg' or 'run_bg' to run the specified app with the given
+#    options in foreground or background respectively. Variable '$1' contains
+#    path of the file to open. If run_bg is used the app is detached and
+#    started in the background in silent mode. If the app is not installed
+#    (i.e. is not on your PATH), it is silently skipped and the script tries
+#    next 'run_bg' or 'run_fg'.
+#
+#    The 'run_bg' vs. 'run_fg' depends on personal preference and type of app,
+#    e.g., I would start vim (CLI) in the foreground but Sublime Text (GUI) in
+#    the background.
+#
+# 2. Detached apps are not killed when nnn exits. Use kill(1) or killall(1) to
+#    to stop console based background apps.
+#
+# 3. nlay is OVERWRITTEN during nnn upgrade. You can store your custom nlay in a
+#    location other than the default and have an alias with nnn option '-p' to
+#    invoke it. Remember it might break or lack new capabilities added to nlay
+#    in future releases. Check the file diff once in a while.
+#
+# Please note that this is not the original nlay script, but Alpine version
+# rewritten to be compatible with any POSIX compliant shell, not just Bash/ZSH.
