                     79: Usage is for lpml file to come in through standard input.
                     80: 1st argument is the mode of parsing:
                     81:     install,configinstall,build,rpm,dpkg,htmldoc,textdoc,status
                     82: 2nd argument is the category permissions to use:
                     83:     typical choices: runtime,development
                     84: 3rd argument is the distribution:
                     85:     typical choices: default,redhat6.2,debian2.2,redhat7
                     86: 4th argument is to manually specify a sourceroot.
                     87: 5th argument is to manually specify a targetroot.
                     88: 
                     89: Only the 1st argument is mandatory for the program to run.

                   1682: =head1 DESCRIPTION
                   1683: 
                   1684: The general flow of the script is to get command line arguments, run through
                   1685: the XML document three times, and output according to any desired mode:
                   1686: install, configinstall, build, rpm, dpkg, htmldoc, textdoc, and status.
                   1687: 
                   1688: A number of coding decisions are made according to the following principle:
                   1689: installation software must be stand-alone.  Therefore, for instance, I try
                   1690: not to use the GetOpt::Long module or any other perl modules.  (I do however
                   1691: use HTML::TokeParser.)  I also have tried to keep all the MODES of
                   1692: parsing inside this file.  Therefore, format_TAG subroutines are fairly
                   1693: lengthy with their conditional logic.  A more "elegant" solution might
                   1694: be to dynamically register the parsing mode and subroutines, or maybe even work
                   1695: with stylesheets.  However, in order to make this the installation back-bone
                   1696: of choice, there are advantages for HAVING EVERYTHING IN ONE FILE.
                   1697: This way, the LPML installation software does not have to rely on OTHER
                   1698: installation software (a chicken versus the egg problem).  Besides, I would
                   1699: suggest the modes of parsing are fairly constant: install, configinstall,
                   1700: build, rpm, dpkg, htmldoc, textdoc, and status.
                   1701: 
                   1702: Another coding decision is about using a multiple pass-through approach to
                   1703: parsing the lpml file.  This saves memory and makes sure the server will never
                   1704: be overloaded.  During the first pass-through, the script gathers information
                   1705: specific as to resolving what tags with what 'dist=' attributes are to be used.
                   1706: During the second pass-through, the script cleans up white-space surrounding
                   1707: the XML tags, and filters through the tags based on information regarding the
                   1708: 'dist=' attributes (information gathered in the first pass-through).
                   1709: The third and final pass-through involves formatting and rendering the XML
                   1710: into whatever XML mode is chosen: install, configinstall, build, rpm, dpkg,
                   1711: htmldoc, textdoc, and status.
                   1712: 
                   1713: The hierarchy mandated by the DTD does not always correspond to the hierarchy
                   1714: that is sensible for a Makefile.  For instance, in a Makefile it is sensible
                   1715: that soft-links are installed after files.  However, in an LPML document, it
                   1716: is sensible that files and links be considered together and the writer of the
                   1717: LPML document should be free to place things in whatever order makes best
                   1718: sense in terms of LOOKING at the information.  The complication that arises
                   1719: is that the parser needs to have a memory for passing values from
                   1720: leaves on the XML tree to higher-up branches.  Currently, this memory is
                   1721: hard-coded (like with the @links array), but it may benefit from a more
                   1722: formal approach in the future.
