; Command file to extract external headers from specified modules, and
; place them into a specified device and ufd.  Listings are optionally
; generated and, if generated, deleted after printing.  This command file
; uses the same .MOD file used to build a library.  If there is not library,
; a .MOD file is created just the same for this routine to handle.
;
; SUPPRESSED INPUT MODE exists -- description is in .CMD file
; REMOTE MODE exists -- description is listed in .CMD file
;
.; SUPPRESSED INPUT MODE:
.; This file may be called from another command file or buffer stuffer
.; using the parameters to initialize certain variables.  This will
.; eliminate the need to query the operator for this information.
.; This is useful when this command file is called by another command
.; file that will be take two hours doing other work before getting
.; around to calling this one.  Thus the operator can take a nap and
.; not have to wait around to answer the questions the variables 
.; need initialization.
.;
.; REMOTE MODE:
.; This file may be run from a different terminal, if you have 
.; access to a buffer stuffer. When this is done, the command
.; file does no interaction with its TI: (which you can't readily
.; get at). Instead, BRO is used to notify the specified terminal
.; of errors and completion. 
.;
.; For either mode, use the following command line.  Leave out <eti>
.; for SUPPRESSED INPUT mode, and specify <eti> for REMOTE mode.
.; The <modfil> parameter must be specified, while the others are
.; optional, and default values will be used.  Note that there can be
.; no ommissions between specified parameters, even if the default is
.; desired for that parameter in between.  Ommissions can only occur
.; when no further specified parameters follow.
.;
.; Invoke with commandline @BUILDEXT <modfil> <lsw> <ldev> <esw> <eti>.
.;
.; <modfil> = dev:[uic]library  (p1) 
.;    This is the .MOD (text) file name.  The device, uic and name of the file
.;    is specified (normal file spec defaults apply).  Do not specify the
.;    extention or version.  This command file will append the .MOD extention
.;    and the latest version will be used.  The .MOD file will contain the name
.;    of the library, into which insertion will occur, in the first line.
.;    The library extention or version should not be specified, only
.;    device, uic, and name, with normal file spec defaults valid.
.;    The second line and onward will contain the names of the source
.;    modules to be compiled (assembled) and inserted into the library.
.;    The extention MUST be specifed.  Normal file spec defaults apply.

.;            continue until n errors have occurred.  If n is not
