.SH OPTIONS
The linker may run in the command line mode or command file modes.  The 
allowed startup linker commands are:  
.TP 
.BI "\-c/\-f"
command line / command file modes 
.TP
.BI "\-p/\-n"
enable/disable echo file.lnk input to stdout 
.PP
If command line mode is selected, all linker commands come from stdin, if the 
command file mode is selected the commands are input from the specified 
file (extension must be .lnk). 
.PP
After invoking the linker the valid options are:
.B Libraries
.TP
.BI "-k " "library directory path" " (one  definition  per line)"
This specifies one possible path to an object library.  More than one path is
allowed.  
.TP
.BI "-l " "library file specification" " (one  definition  per  line)"
This specifies a possible library file.  More than one file is allowed.  
.PP
.B Relocation
.TP
.BI "-b " "area base address = expression" " (one definition per line)"
This specifies an area base address where the expression may contain constants 
and/or defined symbols from the linked files.  
.TP
.BI "-g "  "global symbol = expression" " (one definition per line)" 
This specifies the value for the symbol where the expression may contain 
constants and/or defined symbols from the linked files.  
.PP
.B Map format:
.TP
.BI "\-m"
Generate a map file (file.map). This file contains a list of the symbols 
(by area) with absolute addresses, sizes of linked areas, and other linking
information.  
.TP
.BI "\-w"
Specifies that a wide listing format be used for the map file.  
.TP
.BI "\-x"
Hexadecimal (default).
.TP
.BI "\-d"
Decimal. 
.TP

.PP
.B Output:
.TP
.BI "\-i"
Intel Hex (file.ihx) image output file.
.TP
.BI "\-s"
Motorola S19 (file.s19) image output file.
.TP
.BI "\-j"
Produce NoICE debug as file (file.noi)
.TP
.BI "\-z"
Produce SDCdb debug as file (file.cdb).
.PP
.B Lists:
.TP
.BI "\-u"
Generate an updated listing file (file.rst) derived from the relocated 
addresses and data from the linker.
.PP
.B Miscellaneous:
.TP
.BI "\-a"
[iram-size] Check for internal RAM overflow.
.TP
.BI "\-v"
[xram-size] Check for external RAM overflow.
.TP
.BI "\-w"
[code-size] Check for code overflow.
.TP
.BI "\-y"
Generate memory usage summary file (file.mem).
.TP
.BI "\-Y"
Pack internal ram.
.TP
.BI "\-A"
[stack-size] Allocate space for stack.
.PP
.B End:
.TP
.BI "-e "
