Linker .map file browser for AVR-GCC

Question

I am looking for a linker map file browser / analyzer, like http://www.sikorskiy.net/prj/amap/ but able to work with AVR-GCC (avr-ld) linker map files.

I am currently doing avr-nm -l --size-sort myproject.elf, after reading eleven years old avrfreaks post
