  [33X[0;0YThese  functions  have been transferred from package [5XAutoDoc[105X where they were
  named [10XAutoDoc_FindMatchingFiles[110X and [10XAutoDoc_CreateDirIfMissing[110X.[133X
  
  [33X[0;0Y[10XFindMatchingFiles[110X  scans  the  given  (by  name) subdirectories of a package
  directory  for  files  with  one  of  the  given extensions, and returns the
  corresponding filenames, as paths relative to the package directory.[133X
  
  [33X[0;0Y[10XCreateDirIfMissing[110X  checks  whether  the given directory exists and, if not,
  attempts to create it. In either case [10Xtrue[110X is returned.[133X
  
  [33X[0;0Y[13XWarning:[113X   this   function  relies  on  the  undocumented  library  function
  [10XCreateDir[110X, so use it with caution.[133X

  [33X[0;0YThis function has been transferred from package [5XRCWA[105X.[133X
  
  [33X[0;0YThis function converts the [5XGAP[105X logfile logfilename to HTML. The extension of
  the input file must be [11X*.log[111X. The name of the output file is the same as the
  one of the input file except that the extension [11X*.log[111X is replaced by [11X*.html[111X.
  There  is a sample CSS file in [11Xutils/doc/gaplog.css[111X, which you can adjust to
  your taste.[133X

  [29X[2XPrintApplicableMethod[102X( [3Xarg[103X ) [32X function
  
  [33X[0;0YThis    function   combines   calls   to   [10XApplicableMethod[110X,   [10XFilenameFunc[110X,
  [10XStartlineFunc[110X and [10XEndlineFunc[110X and prints the location of the file containing
  the  method  found, and a listing of that method. In its simplest form it is
  called  as  [10XPrintApplicableMethod(f,L)[110X  for  a  function  [10Xf[110X  and  a  list of
  parameters  [10XL[110X. Alternatively, it is called as [10XPrintApplicableMethod(f,L,0,n)[110X
