Directory lout/doc/tr.impl This directory contains the Lout source files for the report entitled `The design and implementation of the Lout document formatting language' which has been accepted for publication in Software - Practice and Experience. To produce the report, type the command lout setup s?.? > outfile.ps in this directory. This must be done three times to completely resolve all cross references, although the PostScript file outfile.ps is printable after the first run. Auxiliary files with .li and .ld suffixes will be created in this directory. A copy of the final outfile.ps is included. Jeffrey H. Kingston 22 April 1993
