#!/bin/bash
#
# This script will convert all the jpeg images located in
# /myth/gallery into videos. These videos are placed in the
# directory rooted at /myth/Slideshows. The directory scructure
# of /myth/Slideshows will replicate /myth/gallery. An example
# helps:
#
# /myth/gallery/photos_from_2001/birthday_party/*.jpg
# /myth/gallery/photos_from_2001/summer_vacation/*.jpg
#
# Will generate:
#
# /myth/Slideshows/photos_from_2001/birthday_party.mpg
# /myth/Slideshows/photos_from_2001/summer_vacation.mpg
#
# Other notes:
#
# 1.    If /myth/Slideshows does not exist, it is created
#       automatically.
# 2.    The script "genss.sh" must be in a directory that is
#       on your path. On my machine I put it in /usr/local/bin.
# 3.    These scripts will not spend time re-generating an existing
#       mpg file unless one or more of the corresponding jpg images has
#       a more recent time stamp than the mpg file.
# 4.    The "genss.sh" script defaults to NTSC -- if you need PAL, you
#       need to edit "genss.sh" and set the variable "standard" to PAL
#       near the top of the file. Note that I have not tested the use
#       of PAL, as my environment is NTSC.
# 5.    Temporary files are created in /myth/tmp.
