Skipping functions from entire directories while debugging (e.g. skip all functions from system headers)

So, today I got finally so tired of navigating (or explicitly stepping over) all the internal functions in gdb (you know, all the inline functions from STL containers, from Boost, from this pointer wrapper class, that string class) that I finally googled 'gdb skip system functions'. And guess what, it's been there since gdb 7.12, from 3 years ago, and it's almost trivial, just adding something like this to ~/.gdbinit:

skip -gfi /usr/include/*
skip -gfi /usr/include/*/*
skip -gfi /usr/include/*/*/*
skip -gfi /usr/include/*/*/*/*

 I feel so stu^H^H^Hproud for catching up only 3 years late.
