Each flavour of coff supported in BFD has its own header file
descibing the external layout of the structures. There is also
an internal description of the coff layout (in
- @code{internalcoff.h}) file (@code{}). A major function of the
+ @code{internalcoff.h}). A major function of the
coff backend is swapping the bytes and twiddling the bits to
translate the external form of the structures into the normal
internal form. This is all performed in the
outside world into the internal forms.

DESCRIPTION
This function is called with an a symbol describing the
function to be called, an string which descibes the xtor type,
- eg something like "CTOR" or "DTOR" would be fine. And the bfd
+ e.g., something like "CTOR" or "DTOR" would be fine. And the bfd
which owns the function. Its duty is to create a section
called "CTOR" or "DTOR" or whatever if the bfd doesn't already
have one, and grow a relocation table for the entry points as
