   All tree walking commands support file selection this way:

   1. short format with ONE directory tree and MANY file name patterns:
      src1dir .cpp .hpp .xml bigbar !footmp
   2. short format with a list of explicite file names:
      letter1.txt revenues9.xls report3\turnover5.ppt
   3. long format with MANY dir trees and file masks PER dir tree:
      -dir src1 src2 !src\save -file foosys .cpp -dir bin5 -file .exe

   For detailed help on file selection, type "sfk help select".

   * and ? wildcards are supported within filenames. "foo" is interpreted
   as "*foo*", so you can leave out * completely to search a part of a name.
   For name start comparison, say "\foo" (finds foo.txt but not anyfoo.txt).

   When you supply a directory name, by default this means "take all files".

      sfk list mydir                lists ALL  files of mydir, no * needed.
      sfk list mydir .cpp .hpp      lists SOME files of mydir, by extension.
      sfk list mydir !.cfg          lists all  files of mydir  EXCEPT .cfg

   general options:
      -tracesel tells in detail which files and/or directories are included
                or excluded, and why (due to which user-supplied mask).
      -nosub    do not process files within subdirectories.
      -nocol    before any command switches off color output.
      -quiet    or -nohead shows less output on some commands.
      -hidden   includes hidden and system files and dirs.
      For detailed help on all options, type "sfk help options".

   type "sfk ask word1 word2 ..."   to search ALL help text for words.
   type "sfk dumphelp"              to print  ALL help text.
