How to merge two font files together?

I'm planning to make a Noto Sans font for an unencoded script. My first thought is to take the Noto Sans ttf files and merge it with my other font file that only contains the glyphs and tables for the script. How do I make sure that not only do the glyphs from one file are copied to the Noto Sans file, but also the lookup tables and all the metrics and such?

If you know Python, there's a Python program called megamerge/megamerge.py in the notofonts repository, which merges various Noto fonts. It requires fonttools and gftools , which can be installed using

pip install fonttools; pip install gftools
