{chletter}[2010/10/10 v2.0 Swiss letter document class] The chletter class is suited for typesetting letters with letterhead corresponding to the Swiss norm SN 010130. The default letterhead fits into ISO 269 C5 & C6/5 windowed envelopes, both right windowed and left windowed. This class is mostly compatible with the standard LaTeX2e classes. It is not limited to letters and may be used as a generic document class. Its basic usage is very simple and user friendly. It is appropriate to quickly typeset casual documents and letters. However the class is highly configurable and may be used within complex setups to provide automated letters composition. The chletter code is very compact and highly optimized, dropping the obsolete legacy (namely LaTeX 2.09) for the sake of efficiency.
