1) $SPLSRC and $SRCDIR should be changed to $SRC_DIR. These are
vestiges of an earlier version of the script and were missed when
it was updated. Additionally ensure the directory is created.
2) The 'fail' function should take an integer argument for the
error code to return. Otherwise 0 (success) will be mistakenly
returned and errors will we incorrectly suppressed. The error
code should be meaningful enough to determine where the script
failed.
