.Sh DESCRIPTION
.Nm
is a utility program that manipulates libraries of object modules.
.Nm
makes it possible to create a library of commonly used functions. This
library can be very efficiently searched and any modules required by the
program can be extracted from the library and placed in the output file.
.Pp
Since several object 
modules may be contained in the same original source file,
.Nm
keeps track of the name of the file that each module comes from.
This allows all the modules associated with a file to be manipulated
without tediously typing in the name of each module. Options may be
specified individually or together.
.Sh OPTIONS
.Bl -tag -width indent
.It Fl A
This option tells
.Nm
to add the specified files to the library. The symbol dictionary is updated
to include the names of symbols defined in the object modules in the files.
If none of the options 
.Fl A , D , 
or
.Fl X
are given, the default is to assume option 
.Fl A .
To create a library from a set of object files, use the command:
.Pp
.Dl Nm Fl A Ar MYLIB.LIB Ar LIBSRC1.OBJ Ar LIBSRC2.OBJ Ar LIBSRC3.OBJ
.Pp
which will create a library file called 
.Ar MYLIB.LIB
and add all the modules
from the three object files. If 
.Ar MYLIB.LIB
already existed, the modules
from the three object files will be added to the library.
.It Fl D
The modules in the library that originally came from the named files are
deleted from the library. Modules must be deleted before being replaced
with new ones.
.Pp
The following example shows how to remove the modules associated with an
object file.
.Pp
.Dl Nm Fl D Ar MYLIB.LIB Ar LIBSRC3.OBJ
.Pp
All of the modules associated with the file
.Ar LIBSRC3.OBJ
will be deleted from the library. 
.Pp
This example shows how to replace a file in a library.
.Pp
.Dl Nm Fl D Ar MYLIB.LIB Ar LIBSRC2.OBJ
.Dl Nm Fl A Ar MYLIB.LIB Ar LIBSRC2.OBJ
.Pp
The modules associated with 
.Ar LIBSRC2.OBJ
will first be deleted from the library and then added from the new version
of the file. The following options display information about the library
file after the modification arguments, if any, have been processed.
.It Fl F
This option must be followed by the name of a text file. The file will be
read and arguments will be extracted from the file. When the end of file
is reached, additional arguments are again extracted from the command
line. This allows more object modules than will fit on the standard command
line to be processed at one time.
.Pp
For example, these commands add all files with a 
.Ar .OBJ
extension to the library.
.Pp
.Dl Nm DIR Ar *.OBJ > Pa OBJLIST
.Dl Nm Fl A Ar MYLIB.LIB Fl F Ar OBJLIST
.It Fl L
This option causes a list of the files in the library to be printed.
Associated with each file name is a file number. This number will also
appear in the symbol listing which indicates which file contains the
module that defines that symbol. This command will display the names
of all files added to a library.
.Pp
.Dl Nm  Fl L Ar MYLIB.LIB
.Pp
This command adds two files to the library.
.Pp
.Dl Nm Fl AL Ar MYLIB.LIB Ar LIBSRC1.OBJ Ar LIBSRC2.OBJ
.Pp
After the files are added, a list of all the files in the library will
be printed.
.It Fl S
This option causes the dictionary of symbols contained in the library to
be printed. The dictionary is printed in alphabetical order. The number
of the file that defined the symbol along with the offset into the
library of the module that defined it are printed beside the symbol name.
.It Fl X
The modules in the library that originally came from the named files
are extracted from the library and placed into files with the same
name. After extraction, the modules in the library are deleted.
.Pp
The following example extracts two files from a library.

.Dl Nm Fl X Ar MYLIB.LIB Ar LIBSRC3.OBJ Ar LIBSRC1.OBJ
