## @deftypefn {Function File} {} mkoctfile [-options] file @dots{}
## 
## The @code{mkoctfile} function compiles source code written in C,
## C++, or Fortran.  Depending on the options used with @code{mkoctfile}, the
## compiled code can be called within Octave or can be used as a stand-alone
## application.
##
## @code{mkoctfile} can be called from the shell prompt or from the Octave
## prompt.
##
## @code{mkoctfile} accepts the following options, all of which are optional
## except for the file name of the code you wish to compile:
##
## @table @samp
## @item -I DIR
## Add the include directory DIR to compile commands.
##
## @item -D DEF
## Add the definition DEF to the compiler call.
##
## @item -l LIB
## Add the library LIB to the link command.
##          
## @item -L DIR
## Add the library directory DIR to the link command.
##
## @item -M
## @itemx --depend 
## Generate dependency files (.d) for C and C++ source files.
##          
## @item -c
## Compile but do not link.
##
## @item -g
## Enable debugging options for compilers.
##
## @item -o FILE
## @itemx --output FILE  
## Output file name.  Default extension is .oct
## (or .mex if --mex is specified) unless linking
## a stand-alone executable.
##
## @item -p VAR
## @itemx --print VAR
## Print the configuration variable VAR.  Recognized variables are:
