+.SH NAME
+led \- link editor
+.SH SYNOPSIS
+.B led
+[ option ] ... file ...
+.SH DESCRIPTION
+.I Led
+is a link editor for object modules,
+created by one of the ACK assemblers.
+It combines several
+object programs into one,
+resolves external references,
+and searches archives.
+In the simplest case several object
+.I files
+are given, and
+.I led
+combines them, producing
+an object module which can be either
+fed into a machine specific conversion program
+or become the input for a further
+.I led
+run.
+(In the latter case, if there are no unresolved references,
+the
+.B \-r
+option must be given
+to preserve the relocation information.)\ 
+The resulting object file of
+.I led
+is named
+.BR a.out .
+.PP
+The argument routines are concatenated in the order specified.
+The entry point of the output is the
+beginning of the first routine.
+.PP
+If an argument is an archive, its table of contents is searched
+for names which are undefined at the point at which the argument
+is encountered in the argument list.
+This procedure is repeated as long as unresolved references are
+satisfied.
+.PP
+.I Led
+understands several options.
+The flags
+.BR \-c ,
+.BR \-r ,
+.BR \-s ,
+and
+.B \-u
+should appear before the file names.
+.TP
+.BI \-a dd:nnnn
+The alignment of section
+.IR dd ,
+where
+.I dd
+is a decimal number,
+is set to
+.IR nnnn .
+If
+.I nnnn
+starts with `0x', it is hexadecimal,
+else if its starts with `0b', it is binary,
+else if it starts with `0', it is octal,
+else it is decimal.
+.TP
+.BI \-b dd:nnnn
+The base addres in the machine of section
+.IR dd ,
+is set to
+.IR nnnn .
+The previous remarks about
+.I dd
+and
+.I nnnn
+apply.
+.TP 
+.B \-o
+The
+.I name
+argument after
+.B \-o
+is used as the name of the
+.I led
+output file, instead of
+.BR a.out .
+.TP 
+.B  \-r
+Generate relocation information in the output file
+so that it can be the subject of another
+.I led
+run.
+This flag suppresses the `Undefined:' diagnostic.
+.TP
+.B \-c
+Only effective in combination with
+.BR \-r .
+Indicates that relocatable output must be produced, but commons must
+be resolved.
+This may be useful for machines that need a last relocation step
+at load time.
+.TP
+.B  \-s
+`Strip' the output, that is, remove the name table
+and relocation information to save space (but impair the
+usefulness of the debuggers).
+.TP 
+.B  \-u
+Take the following argument as a symbol and enter
+it as undefined in the name table.
+This is useful for loading wholly from a library,
+since initially the name table is empty
+and an unresolved reference is needed
+to force the loading of the first routine.
