-Textfile/Substfile builder for SCons.
-
-    Create file 'target' which typically is a textfile.  The 'source'
-    may be any combination of strings, Nodes, or lists of same.  A
-    'linesep' will be put between any part written and defaults to
-    os.linesep.
-
-    The only difference between the Textfile builder and the Substfile
-    builder is that strings are converted to Value() nodes for the
-    former and File() nodes for the latter.  To insert files in the
-    former or strings in the latter, wrap them in a File() or Value(),
-    respectively.
-
-    The values of SUBST_DICT first have any construction variables
-    expanded (its keys are not expanded).  If a value of SUBST_DICT is
-    a python callable function, it is called and the result is expanded
-    as the value.  Values are substituted in a "random" order; if any
-    substitution could be further expanded by another subsitition, it
-    is unpredictible whether the expansion will occur.
