If "/" is the delimiter then the initial "m" is optiona
+l.  With
               the "m" you can use any pair of non-alphanumeric, non-w
+hite-
               space characters as delimiters.  This is particularly u
+seful
               for matching path names that contain "/", to avoid LTS 
+(leaning
               toothpick syndrome).  If "?" is the delimiter, then the
+ match-
               only-once rule of "?PATTERN?" applies.  If "'" is the d
+elim-
               iter, no interpolation is performed on the PATTERN.
...
               If the delimiter chosen is a single quote, no interpola
+tion is
               done on either the PATTERN or the REPLACEMENT.  Otherwi
+se, if
               the PATTERN contains a $ that looks like a variable rat
+her than
               an end-of-string test, the variable will be interpolate
+d into
               the pattern at run-time.  If you want the pattern compi
+led only
               once the first time the variable is interpolated, use t
+he "/o"
               option.  If the pattern evaluates to the empty string, 
+the last
               successfully executed regular expression is used instea
+d.  See
               perlre for further explanation on these.  See perllocal
+e for
               discussion of additional considerations that apply when
+ "use
               locale" is in effect.
