I was just working on importing an existing code tree into my HW directory for arduino zero.
Rather than re-arrange the files, I wanted to pass include directives to the compiler for specific directories. But the only option is relative paths to the compiled file. That cause includes like -I../../../sam0/utils/header_files -I../../../utils/header_files -I../../../../utils/header_files -I./sam0/utils/header_files Depending how deep in the tree the compiler was working. it'd be nice to have an option to have include paths that were absolute and referenced to the egg.yml file Also, since I had a few dozen of these, it would be nice to have the egg.cflags: token accept the \ symbol to extend to multiple lines.
