g:CSApprox_verbose_level *g:CSApprox_verbose_level*
While running, CSApprox sets 'verbose' to this value (default 1). This
allows CSApprox to default to warning whenever something might be wrong,
but allows the user to disable this behavior if he wants. The most
important messages will be shown at verbosity level 1, some less important
ones will be shown at verbosity level 2. Internal errors and
configuration errors are shown regardless of verbosity level.
When CSApprox is run, the 'verbose' option will be temporarily raised to
the value held in this variable unless it is already greater. The default
value is 1, which allows CSApprox to default to warning whenever something
is wrong, even if it is recoverable, but allows the user to quiet us if he
wants by changing this variable to 0. The most important messages will be
shown at verbosity level 1; some less important ones will be shown at
higher verbosity levels.
