+.SH NAME
+em_cg \- EM to assembly code translator
+.SH SYNOPSIS
+em_cg [-d\fIn\fP] [-p\fIn\fP] [-w\fIn\fP] [-u\fIfile\fP] [ infile [ outfile ] ]
+.SH DESCRIPTION
+Em_cg reads a compact EM-program, argument or standard input,
+and produces an assembly program on argument or standard output
+for the machine that is in its name.
+Flags recognized are:
+.IP -d\fIn\fP
+Run in debugging mode, debugging level \fIn\fP,
+only possible when the translator is compiled in the right way.
+.IP -p\fIn\fP
+Set the ply to \fIn\fP, default 1.
+The ply is the maximum lookahead depth the code generator may take.
+Effects of this flag are machine dependent.
+.IP -w\fIn\fP
+Set the weight percentage for size to \fIn\fP %, default is 50.
+This sets the size/time tradeoff in the codegenerator.
+Effects are again machine dependent.
+.IP -u\fIfile\fP
+Take the \fIfile\fP as a bitmap giving 1 bits for untested code rules
+and write the \fIfile\fP at end of code generation,
+substituting zero bits for rules used.
+Give a list of untested rules on standard error, unless the -u
+was given as -U.
+Only possible if the -d flag was given to cgg(VI).

+.SH NAME
+cgg \- Code table translating utility
+.SH SYNOPSIS
+cgg [-c] [-d] [-v] table
+.SH DESCRIPTION
+cgg translates a machine description table into the internal
+structures needed by em_cg.
+Flags recognized are:
+.IP -c
+Write one of the largest arrays in binary form on the file code.
+The resulting code generator must be run in the same directory,
+but compile time of the code generator will be less.
+Useful during table debugging.
+.IP -d
+Generate pseudo code for table debugging.
+This gives better information when the resulting code generator
+is run with the debug flag on.
+It also generates the file lineset that can be used as the
+bittable described under the -u option of em_cg(VI).
+.IP -v
+Give statistics about table usage at end of program.
+Normally only the tables that have been used more than 75%
+are reported.
