While answering questions that Jim Warner had about the front end monitoring in the 2.9 rcg, we noted that he wanted a better way to set the monitored bit than a text editor.

So I updated the sdf_set_monitor script to optionally limit the list of channels it operates on. Now you can build a list of channels that you want to (un)monitor, save it as a file and quickly change the monitoring flag in the safe.snap file.

Examples:

Set all channels to be monitored:

sdf_set_monitor 1 safe.snap

Set all channels to not be monitored:

sdf_set_monitor 0 safe.snap

Set some channels to be monitored (leaving the rest as is):

sdf_set_monitor -c ~/monitor_list.txt 1 safe.snap

Set some channels to not be monitored (leaving the rest as is):

sdf_set_monitor -c ~/dont_monitor_list.txt 0 safe.snap

You need to create a file with the list of channels.  It reads one channel per line, and only reads until the first space, tab, ... so you can actually hand it lines from a snap file and it will extract the channels you give it.

This change is LHO only right now as I lack commit rights to the proper svn repository.
