       autoheader2.13  -  creates  a  template  file of C #define’s for use by


       autoheader2.13 [  --help  |  -h  ]  [  --localdir=dir  |  -l  dir  ]  [
       --macrodir=dir | -m dir ] [ --version ]


       The  autoheader2.13  program  can  create  a template file of C #define
       statements   for   configure   to   use.    If   invokes
       AC_CONFIG_HEADER(FILE),  autoheader2.13  creates;  if multiple
       file  arguments  are  given,  the  first  one  is   used.    Otherwise,
       autoheader2.13 creates

       If  you  give  autoheader2.13 an argument, it uses that file instead of and writes the header file to the standard output  instead
       of  to   If  you give autoheader2.13 an argument of -, it
       reads the standard input instead of and writes the  header
       file to the standard output.

       autoheader2.13  scans and figures out which C preprocessor
       symbols it might define.  It copies comments  and  #define  and  #undef
       statements  from  a  file  called  acconfig.h,  which comes with and is
       installed with Autoconf.  It also uses a file called acconfig.h in  the
       current  directory,  if  present.   If  you  AC_DEFINE  any  additional
       symbols, you must create that file with entries for them.  For  symbols
       defined   by   AC_CHECK_HEADERS,  AC_CHECK_FUNCS,  AC_CHECK_SIZEOF,  or
       AC_CHECK_LIB, autoheader2.13 generates comments and  #undef  statements
       itself rather than copying them from a file, since the possible symbols
       are effectively limitless.

       The file that autoheader2.13 creates contains mainly #define and #undef
       statements  and  their accompanying comments.  If ./acconfig.h contains
       the string @TOP@, autoheader2.13  copies  the  lines  before  the  line
       containing   @TOP@  into  the  top  of  the  file  that  it  generates.
       Similarly, if ./acconfig.h contains the string @BOTTOM@, autoheader2.13
       copies  the  lines after that line to the end of the file it generates.
       Either or both of those strings may be omitted.

       An alternate way to produce the same effect  is  to  create  the  files  (typically  and/or  in  the  current
       directory.  If they exist, autoheader2.13 copies them to the  beginning
       and end, respectively, of its output.  Their use is discouraged because
       they have file names that contain two periods, and so can not be stored
       on  MS-DOS;  also, they are two more files to clutter up the directory.
       But if you use the  --localdir=DIR  option  to  use  an  acconfig.h  in
       another  directory,  they  give  you a way to put custom boilerplate in
       each individual

       autoheader2.13 accepts the following options:


       -h     Print a summary of the command line options and exit.


       -l DIR Look for the package files aclocal.m4 and  acconfig.h  (but  not
      and  in  directory  DIR  instead  of in the
              current directory.


       -m DIR Look for the installed macro files and acconfig.h  in  directory
              DIR.  You can also set the AC_MACRODIR environment variable to a
              directory; this option overrides the environment variable.

              Print the version number of Autoconf and exit.
