No need to delete cue file if I delete the whole dir; also, it will be used in this version.
Replace helper scripts with native calls to abcde.
Update the first call to abcde to keep the directory between calls. Add error checking for the abcde calls.
Add some error checking after abcde runs and change the transcode to not use the FLAC file.

If I don't delete the WAV files, and then run abcde to ostensibly
read from the 1-file FLAC, it will see the WAV files and say
"Finished" without doing anything.
Thus, it is possble for abcde to complete with a 0 exit status, while
having done absolutely nothing and created nothing.

So,
* Perform error checking after each abcde run to ensure that the
file has been created.
* Change the second abcde run (transcode) to not pull from the
FLAC file, so that it might pull from the rip and cue.
Allow clobbering with copies throuhout and reduce redundant structures.

There is no need to prevent copying over a FLAC or OGG file.
Reduced the redundancy "if a then copy b to c, else copy b to d" with
"if a then i=c else i=d; copy b to i".
Rolled back changes in the abcde execution, because a change in the abcde.conf file made this unnecessary.
Do away with rip collision check on NAS (for now?)
Renamed ogg script to the more correct vorbis, and changed the internal option to vorbis as well.
Create a script to convert a 1-file FLAC to a 1-file Vorbis in an Ogg container.
Make some notes of what to do in digitize-cd.
Put error-detecting code into the atomic helper scripts.
Put helper scripts back in, change error detection code.
Comment out manual eject, since abcde auto-eject is working now.
Pause so output can be reviewed before closing digitize-cd window.
Comment and todo: to only pause if it maks sense.
Disable debug in main CD helper scripts.
Update header in preparation for 2.0. Disable debug. Add commands to check.
Check for existance of the input file before running.
Moved to DVD phase of project; change files open in project file.
Move from test to point to real DVD digitizing script.
