+Example Writing:
+
+[ ] Think up better introductory examples
+[ ] Example of symbol sets with instances that don't need names
+[ ] Example of more complex data initialization via the hook
+
+
+
+Vetting:
+
+Compilers: CL,    GCC,   CLANG
+Linkers:   LINK,  GCC,   CLANG
+OSs:       Win32, Linux, Mac
+           (COFF) (ELF)  (MACHO)
+
+[ ] Check configurations for accurate section virtual sizes
+    Win32{
+     link:              -INCREMENTAL:NO
+     clang (as linker): -Xlinker -INCREMENTAL:NO
+     All combinations of CL, LINK, CLANG work so far so long as the above
+     options are used.

+[ ] Check configurations for link time optimization removal of symbols
+
+
+
+Development:
+
+[ ] Small as possible binary parser for "selfimg" purposes
+
+
+
+Structure Research:
+
+[ ] Object file editing for improved memory layout & symbol id references
+    [ ] Setup count and base pointer symbols
+    [ ] Learn how to put the symbol data into .data and relink everything
+    [ ] Setup id symbols & editing to give them values
+    [ ] Eliminate the "raw" version of symbols
+    
+
+[ ] Do I want to maintain a pair of versions one with object file editing
+    and one without?
+[ ] Explore the tradeoff of using the hook for more complex data initialization
+[ ] Could Symbol Sets syntax be organized in such a way that it's just a data
+    section and type wrapped in a macro?
+[ ] How does this hold up when multiple DLLs or SOs are involved?
+
+
+
+Support Tools:
+
+[x] see data section size and layout info
+[ ] dump binary as hex from a data section
+[ ] see symbols inside data sections
+[ ] see symbols by name
+[ ] count of symbols in symbol set
+[ ] display of string and integer data in symbol from symbol set
+[ ] size of types
