## SCRIPT: 02s_multi-movie-files_PLAY-in-Smplayer_for-loop-makeTmpPlaylistFile.sh
##
## PURPOSE: Plays SELECTED movie files in the current directory.
##          Plays the files with 'smplayer'.
##
## METHOD:  In a 'for' loop, builds a play-list file using the names of
##          the selected movie files.
##
##          Uses 'zenity --info' to show some info on how to control
##          movie playback with 'smplayer'.
##
##          Passes the playlist file to 'smplayer'.
##
## HOW TO USE: In Nautilus, navigate to a directory of movie files, and
##             select the files to play. (Can use the Ctl key or
##             the Shift key to select multiple files.)
##             Then right-click on the selected files in the directory,
##             and choose this Nautilus script to run (name above).
##
##        REFERENCE:  Based on the similar AUDIOtools script
##             08s_multiplay_mp3s_selectedShuffled_Smplayer.sh

## Created: 2011apr20
## Changed: 2011jul07 Removed use of a MOVIENAMES="$@" method. In its place,
##                    we use a 'for' loop, WITHOUT the 'in' phrase, to handle
##                    filenames with embedded spaces and build a playlist file.
##                    Ref: man bash
## Changed: 2012may24 Changed script name in comments above and touched up
##                    the comments. Changed some indenting below.
## Changed: 2012oct01 Changed script name from '-playlistFile' to
##                    '-makeTmpPlaylistFile' --- and 'PLAY_Smplayer' to
##                    'PLAY-in-Smplayer'.

## Put the selected filenames in the 'play list' file.
##
## We use 'echo' to put the
## filenames into the playlist file.
##
## NOTE1: Smplayer seems to need the string 'file://'
##        prefixed on fully-qualified filenames.
##
## We could build the a FILENAMES list of filenames
## with a 'for' loop, like MP3NAMES is built
## in the AUDIOtools script
##   07t_multiplay_mp3s_allOfDir_Totem.sh
