+.SH NAME
+em_cemcom.ansi \- ANSI C to EM compiler
+.SH SYNOPSIS
+\fB~/em/lib.bin/em_cemcom.ansi\fP [\fIoptions\fP] \fIsource \fP[\fIdestination
+.SH DESCRIPTION
+\fICemcom\fP is a compiler that translates C programs
+into EM compact code.
+The input is taken from \fIsource\fP, while the
+EM code is written on \fIdestination\fP.
+If either of these two names is "\fB-\fP", standard input or output respectively
+is taken.
+When the preprocessor is invoked to run stand-alone, \fIdestination\fP
+needs not be specified.
+.br
+\fIOptions\fP is a, possibly empty, sequence of the following combinations:
+.IP \fB\-D\fIname\fR=\fItext\fR
+.br
+define \fIname\fR as a macro with \fItext\fR as its replacement text.
+.IP \fB\-D\fIname\fR
+.br
+the same as \fB\-D\fIname\fR=1.
+.IP \fB\-I\fIdirname\fR
+.br
+insert \fIdirname\fR in the list of include directories.
+.IP \fB\-M\fP\fIn\fP
+set maximum identifier length to \fIn\fP.
+.IP \fB\-g\fP
+produce a DBX-style symbol table.
+.IP \fB\-n\fR
+do not generate EM register messages.
+The user-declared variables are not stored into registers on the target
+machine.
+.IP \fB\-L\fR
+don't generate the EM \fBfil\fR and \fBlin\fR instructions
+that usually are generated to enable
+an interpreter to keep track of the current location in the source code.
+.IP \fB\-p\fR
+generate code at each procedure entry to call the routine
+.BR procentry ,
+and at each return to call the routine
+.BE procexit .
+These routines are supplied with one parameter, a pointer to a
+string containing the name of the procedure.
+.IP \fB\-A\fR[\fIfile\fR]
+.br
+if \fIfile\fR is not given, generate a list
+of makefile dependencies and write them to the standard output.
+If \fIfile\fP is given,
+generate the list of makefile dependencies on file \fIfile\fP.
+.IP \fB-i\fR
+when generating makefile dependencies, do not include files from
+/usr/include.
+.IP \fB-m\fR
+when generating makefile dependencies, generate them in the following format:
+.RS
+.IP "file.o: file1.h"
+.RE
+.IP ""
+where "file.o" is derived from the source file name. Normally, only a list
+of files included is generated.
+.IP \fB\-R\fR
+interpret the input as restricted C (according to the language as
+described in \fIThe C programming language\fR by Kernighan and Ritchie.)
+.IP \fB\-U\fIname\fR
+.br
+get rid of the compiler-predefined macro \fIname\fR.
+.IP \fB\-V\fIcm\fR.\fIn\fR,\ \fB\-V\fIcm\fR.\fIncm\fR.\fIn\fR\ ...
+.br
+set the size and alignment requirements.
+The letter \fIc\fR indicates the simple type, which is one of
+\fBs\fR(short), \fBi\fR(int), \fBl\fR(long), \fBf\fR(float), \fBd\fR(double),
+\fBx\fR(long double) or
+\fBp\fR(pointer).
+The \fIm\fR parameter can be used to specify the length of the type (in bytes)
+and the \fIn\fR parameter for the alignment of that type.
+Absence of \fIm\fR or \fIn\fR causes the default value to be retained.
+To specify that the bitfields should be right adjusted instead of the
+default left adjustment, specify \fBr\fR as \fIc\fR parameter.
+.IP \fB\-w\fR
+suppress warning messages.
+.IP \fB\-s\fR
+suppress stricts.
+.IP \fB\-a\fR
+suppress warnings and stricts.
+.IP \fB\-o\fR
+suppress warnings and stricts about old-style.
+.IP \fB\-\-\fItext\fR
+.br
+where \fItext\fR can be either of the above or
+a debug flag of the compiler (which is not useful for the common user.)
+This feature can be used in various shell scripts and surrounding programs
+to force a certain option to be handed over to \fBcemcom\fR.
