Hossein ea5641baee Updated README.md files to represent current code / use Markdown format
Previously, all of the README files have been renamed to README.md
and now, the contents of these files were changed to use Markdown
format. Other than format inconsistency, some README.md files lacked
information about modules, or were out of date. By using LibreOffice
/ OpenOffice wiki and other documentation websites, these files were
updated. Now every README.md file has a title, and some description.
The top-level README.md file is changed to add links to the modules.
The result of processing the Markdown format README.md files can be
seen at: https://docs.libreoffice.org/

# Import Filter for File Format of Lotus Word Pro (lwp)
## Description
The import is not direct, but via an intermediate format: StarOffice
XML, the predecessor of ODF (yes, the code is old). The entry point to
the filter is class LotusWordProImportFilter (refer to Source code
section), but that just hooks up the necessary machinery for processing
StarOffice XML produced by the filter. The real fun starts in function
`ReadWordproFile()` (`source/filter/lwpfilter.cxx`); this function
initializes the parser (class `Lwp9Reader`) and the SAX XML handler that
produces the output (class `XFSaxStream`). The Lwp9Reader class then does
the actual parsing.
If the module is built with debug level greater than 0, it is possible
to examine the intermediate XML: set environment variable
`DBG_LWPIMPORT_DIR=` to an existing directory and, on opening an lwp
document, a file named `lwpimport.xml` will be created in that directory.
## Source Code
### Module Contents
* `inc`: module-global headers (can be included by any file in source)
* `qa`: `cppunit` tests
* `source`: the filter itself
* `util`: UNO passive registration config
### Source Contents
* `filter`: `lwp` document format parser
* `filter/LotusWordProImportFilter.cxx`: the entry point to the filter
* `filter/xfilter`: export to StarOffice XML
