+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.
