	* ''performance'': compare instantiation and evaluation performance of python vs C. Ben has a hypothesis that we can preserve the excellent performance and scalability of ascend relation instantiation and evaluation (while using python) if we try. Would require a python implementation of our instantiator; ascend's for loops are not procedural, so they don't map neatly to python classes as proxies for ascend models.		* ''performance'': compare instantiation and evaluation performance of python vs C.

			== Continued work ==

			As discussed with Ben, the following are the tasks that are to be done for follow-on work.

			# Enable to write output in ascend format to make the transformations comprehensive for others.
			# Provide a makefile or shell (sh) script that shows in one place the complete build and test starting from just the sources and the tar files for the external packages used.

-'''Final Report
+'''Final Report 22 Aug'''
-Added a detailed final report in the Progress folder with future possible development.
+The following points describe the various stages of ply-ascend development and their current status.
-See {{srcbranchdir|bandil|ascend/ply-compilers/Progress/Final22Aug.txt}} for details.
+''Parsing a single file''
-'''22 Aug'''
+Current Status: ply-ascend4 is fully capable of parsing a single ascend file. The file to be parsed is mention in ascMain.py which stores the contents of the file in PARSE_STRING and passes it to the parse function of the related parser file. The symbol table is implemented as a python dictionary structure with Identifier strings as the keys.
-Transformation code for FIX/FREE statement AST fragments completed
+TODO/Possible Development
-'''Overall Progress'''
+Current Status: The AST is passed to OutputAST function in ASTtoString.py which converts it into string form with specified indentation and returns it to be written to StringAST.txt.
-COMPLETED TASKS
+Related Files
-Skeletal lexer and parser - scanner.py and ascParse.py
+''Modifying a tree/ Transformation of FIX/FREE statements''
-Creation of AST node classes - AST_Generator and related cfg files
+Current Status
-Development of mechanism for keeping track of position of various tokens - position.py and ascMain.py
+Related Files
-Development of mechanism for converting the AST to string form - ASTtoString.py and StringAST.txt
+TODO/Possible Development
-Integration of AST nodes in parser for units, dimensions and fractions and converting them to string form - ascParse_AST.py and asc_AST.py, units.py
+''Other Important Development Work''
-IN PROGRESS
+Transformation code for FIX/FREE statement AST fragments completed
-Integration of other AST nodes in parser in progress - ascParse_AST.py
+''Overall Progress''
-Development of tree visitor class
+COMPLETED TASKS
