  The aim of these notes is to generalize Laumon's construction [18] of
automorphic sheaves corresponding to local systems on a smooth, projective
curve $C$ to the case of local systems with indecomposable unipotent
ramification at a finite set of points. To this end we need an extension of the
notion of parabolic structure on vector bundles to coherent sheaves. Once we
have defined this, a lot of arguments from the article "On the geometric
Langlands conjecture" by Frenkel, Gaitsgory and Vilonen [10] carry over to our
situation. We show that our sheaves descend to the moduli space of parabolic
bundles if the rank is $\leq 3$ and that the general case can be deduced form a
generalization of the vanishing conjecture of [10].
