Version 1.5

Previous implementation allowed static files to overwrite existing files
on generate if static-dir was specified and generate-enable-overwrite
was specified. Now, an additional flag
"--generate-static-enable-overwrite" determines if static-dir files
overwrite on generate.

 ## Upcoming Changes
 
+## Version 1.5
+
+Add flag `--generate-static-enable-overwrite`. This flag enables overwriting of
+files from static-dir to generate-dir (if static-dir was specified). Previous
+implementation relied on `--generate-enable-ovewrite` for this behavior.
+
+Minor refactorings related to `printf` and `uintX_t`/`size_t` types.

 Implemented "IF", "ELSEIF", "ELSE", "ENDIF", and "INDEX" for templates.
