Regarding vop_vector

[Aijaz Baig]

Hello

I am trying to understand how the VFS layer within FreeBSD and I was rather
stumped while trying to find where vop_vector was declared. Upon searching
the internet, realized that an awk script is used to "generate" this like
so:

/sys/tools/vnode_if.awk /sys/kern/vnode_if.src -q

So I was wondering if anyone could provide me a (brief would be fine as
well) walk through the memory lane as to why such an 'odd looking' way was
adopted (perhaps it is brilliant but my thick skull is unable to fathom
it's brilliance).

Keen to hear from you experts out there please!
