  23 # The magic generating the regular expression from the temporary
  24 # mapfile containing only star and question mark symbols
  25 #
  26 # The script has to be called as follows:
  27 # nm -gx <file>.o | addsym-mingw.sh <file-with-wildcard-symbols> <temporary-file-where-to-write-the-search-expression-to>
  28 # See tg_shl.mk for an example of how to use the script
  29 #
  30 # Replace every * with .* and every ? with . to get awk expression
  31 # Remove whitespaces and comments in expression
  32 # Put ^ at the beginning of every expression
  33 # Put $ at the beginning of every expression
  34 # Connect them all on one line, separated by |
  35 # Remove | at the end of this regular expression because the last end
  36 # of line was also replaced by |
