libExtractor
============

libExtractor is a simple library for keyword extraction.  libExtractor does
not  support all formats but supports a simple plugging mechanism such that
you  can  quickly  add  extractors  for  additional  formats,  even without
recompiling  libExtractor.   libExtractor  typically ships with one or more
helper-libraries   that   can  be  used  to  obtain  keywords  from  common
file-types.

If  you want to write your own extractor for some filetype, all you need to
do  is  write  a  little  library that implements a single method with this
signature:


KeywordList * extract(const char * filename,
                      char * data,
                      size_t size,
		      KeywordList * prev);


The  filename is the name of the file, data is a pointer to the contents of
the file and size is the size of the file.  The extract method must prepend
keywords  that  it finds to the linked list 'prev' and return the new head.
The  library  must  allocate (malloc) the entry in the keyword list and the
memory for the filename since both will be free'ed by libExtractor once the
application calls freeKeywords.
An example implementation can be found in mp3extractor.c.

notes  
=====  
Please  note,  if you install libextractor in location that the linker does
not   know   about  (i.e.   is  not  in  /etc/ld.so.conf)  you  /must/  set
LD_LIBRARY_PATH=/path/to/libextractor.   It  is  recommended  that you have
this set in your shells initialization file so that it is always set.  This
can  be  accomplished  in  bash  by  adding the following line to ~/.bashrc
export   LD_LIBRARY_PATH="/path/to/libextractor:$LD_LIBRARY_PATH"   or   in
csh/tcsh  by  adding  the following line to ~/.cshrc setenv LD_LIBRARY_PATH
"/path/to/libextractor:$LD_LIBRARY_PATH"
