322    
323    If the C<background> option is specified on the command line, then the
324    standard and error outputs will be directed to files in the temporary
325    directory, using the same suffix as the trace file. So, if the command
326    line specified
327    
328        -user=Bruce -background
329    
330    then the trace output would go to C<traceBruce.log>, the standard output to
331    C<outBruce.log>, and the error output to C<errBruce.log>. This is designed to
332    simplify starting a command in the background.

350    The caller has the option of modifying the tracing scheme by placing a value
351    for C<trace> in the incoming options hash. The default value can be overridden,
352    or the tracing to the standard output can be turned off by suffixing a minus
353    sign to the trace level. So, for example,
354    
355        { trace => [0, "tracing level (default 0)"],
356           ...
357    
358    would set the default trace level to 0 instead of 2, while

360        { trace => ["2-", "tracing level (default 2)"],
361           ...
362

2086    user name, password, and API ID for the relevant account in the hash reference variable
2087    I<$FIG_Config::phone>, using the keys C<user>, C<password>, and C<api_id>. For
2088    example, if the user name is C<BruceTheHumanPet>, the password is C<silly>, and the API ID
2089    is C<2561022>, then the FIG_Config file must contain

2221    Map of search patterns to permission masks. If a directory name matches
2222    one of the patterns, that directory and all its members and subdirectories
2223    will be assigned the new pattern. For example, the following would
2224    assign 01664 to most files, but would use 01777 for directories named C<tmp>.
2225    
2226        Tracer::SetPermissions($dirName, 'fig', 01664, '^tmp$' => 01777);
2227    
2228    The list is ordered, so the following would use 0777 for C<tmp1> and
2229    0666 for C<tmp>, C<tmp2>, or C<tmp3>.

2235    names are matched, not file names.
