    Build Web Sites

SYNOPSIS
    build-web.pl [options]

OPTIONS
    --help  Display this help page.

    --make=*makeprog*
            Specify make program to be used.

            Default value is *make*.

    --srcephysdir=*srcedir*
            Specify the path to the physical directory containing the raw
            html to be processed.

            Default value is *srce*.

    --copy=*[on|off]*
            Write the results to the destination physical directory. If
            --copy=*off* is specified then only the pre and post makefile
            processing is performed.

            --copy=*on* requires that the --srcewebdir, --destphysdir and
            --dirmap options be specified.

    --srcewebdir=*srcewebdir*
            Assume the raw html contained in the srcephysdir is written as
            if the root web directory is *srcewebdir*.

            Requires --copy=*on*

    --destphysdir=*destphysdir*
            Write the results of processing the web site to the physical
            directory *destphysdir*.

            Requires --copy=*on*

    --ssiprocess=*[on|off]*
            Replace the results of Server Side includes (virtual and file
            only) with the contents of the included files. Default value is
            *off*.

            Requires --copy=*on*

    --dirmap=*dirmap.pl*
            Replace occurences of directories using the map specified in the
            *dirmap.pl* script.

            Requires --copy=*on*

    --clean=*[on|off]*
            Remove files from the destphysdir if they do not exist in the
            srcephysdir. Default value is *off*.

            Requires --copy=*on*

DESCRIPTION
    If --copy=*on*, build-web.pl will build a Web Site in a given Physical
    Destination directory from a Web Site contained in a given Source
    directory by copying the files from the Physical Source directory tree
    to the Physical Destination directory tree while remapping directory
    paths as specified in the "DIRMAP.pl" perl program, optionally
    processing Server Side includes, and optionally applying HTML Templates
    to HTML files.

    The Source Web Site exists in the physical directory SRCEPHYSDIR and is
    assumed to be written as it were located on a Web Server in the
    SRCEWEBDIR subdirectory of the Server's root directory.

    This program essentially copies a Physical Source Directory and all
    subdirectories and files to a Destination Directory while performing the
    following tasks.

    If Makefiles exist in the Source Directories, they are 'executed' using
    the make program specified in --make=*makeprog*. Makefiles with the name
    "Makefile.pre" will be executed in the Physical Source directory tree
    before any other processing and can produce new files which will be
    copied to the Physical Destiantion directory tree. Makefiles with the
    name "Makefile.post" will be executed in the Destination directory tree
    and can be used to post process output files generate during the
    build... For example, zip files of the final versions of files in the
    DEST directory tree can be created using post Makefiles. In the case
    where --copy=*off*, the Physical Source and Destination directories are
    the same and post Makefiles are executed in the Physical Source
    directory.

    If the Destination Directories do not exist, they are created.

    Source Files are not copied if their modification times are not
    different from the modification times of the existing Destination files.
    This rule is broken when the template files, include files or Makefiles
    are modified. A Global timestamp is maintained on the last time the
    build was run. If any of the templates, include files, Makefiles are
    modified after the last build, all files are rebuilt.

    The following Source Directories are not copied: CVS, _vti_*

    The following Source Files are not copied:

    Makefile.pre, Makefile.post, Makefile.log, NOWRAP, NOMENU, *-incl.html,
    template.html, template-nomenu.html, .cvsignore, *~, *.bak, *.swp

    If the --clean=*on* option is specified, files which exist in the
    Destination Directories but not in the Source Directories are deleted
    from the Destination Directories.

    Binary Files are copied as is.

    Text Files (not HTML files, i.e. *.htm or *.html) are copied with
    directory remapping as specified in "DIRMAP.pl".

    The DIRMAP.pl program specifies the remapping of referenced directories
    in all Text files.

    These include *.js, *.css, *.htm, *.html, *.psp, *.php, *.asp, *.pl
    files. DIRMAP.pl, which can be named anything, consists of a single Hash
    which specifies the old=>new directory remapping as in:

       $WEBDIRMAP{'/fromdir/'} = '/todir/';

       Note that WEBDIRMAP must contain at least a mapping for the 
       SRCEWEBDIR to a new Web Server directory.

    HTML Files are copied with directory remapping, then Server Side
    includes, then HTML Template wrapping.

    Server Side includes in HTML Files are replaced by the contents of the
    included files. The included files must reside in the SRCEPHYDIR tree
    and are not copied to the Destination Directories. The Server Side
    includes may be either file or virtual, but typically virtual is the
    most useful.

    HTML Templates are specified in special files in the SRCEPHYSDIR
    directory

      template.html - full template including navigation
      template-nomenu.html - template wihthout full navigation

      By default, all HTML files will be wrapped in the template.html template. 
      This may be overridden in each directory by listing the filename on 
      distinct lines in either the NOMENU or NOWRAP text files in each directory. 

      Any file listed in the NOMENU file will be wrapped with the 
      template-nomenu.html file, while any file listed in the NOWRAP file will 
      not be wrapped in a template at all. However, all HTML Files will have 
      their references to directories remapped according to the DIRMAP.pl program.

      Each Template file uses special strings which are replaced by the 
      corresponding parts of the HTML file being wrapped:

         %%DOCTYPE%%
         %%HEAD%%
         %%TITLE%%
         %%LAST_UPDATED%%
         %%BODY%%
         %%FILENAME%%
