The Bonneau identities are a very convenient tool for e.g.
restoring BRST symmetry and deriving renormalization group
equations in content of chiral gauge theories. The background
for the Bonneau identities is Breitenlohner-Maison-'t Hooft-Veltman
dimensional regularization scheme which is reviewed here
with special emphasis to bridge the notational differences between
the Breitenlohner-Maison and the Bonneau papers and identifying
the notions in these references. The Bonneau identities are rederived
but for a general theory and reexpressed in terms of the effective
action, establishing the bridge to the expressions in the
Martin--Sanchez-Ruiz reference. Several new interpretations of
lemmas, theorems and notions are given.
