Installation should be simple, as there is nothing to compile.
You have what is one of three types of packages.

1) A Slackware package
2) A source package
3) A binary distribution


1) Use your package manager of choice (installpkg, xpkgtool, 
   whatever..) Install directory is /opt/HTMLpage. Only extra 
   file is HTMLpage.sh, which is placed into /etc/profile.d. 
   This is done to put the path to the program:
   /opt/HTMLpage/bin
   into your system $PATH. This may seem intrusive, but in 
   fact is is done to avoid just that. Uninstall will remove 
   all remnants of the program without leaving any dangling 
   symlinks from an install script.
     3rd party packages, I believe, belong in /opt, and 
   if you are "careless" enough to simply delete the 
   HTMLpage folder, the script in /etc/profile.d is smart 
   enough not to add the /opt/HTMLpage/bin to your path if 
   it is no longer there.



2) Talk about easy. Once the downloaded package in decompressed,
   just put the folder wherever you want it to stay, then symlink 
   the HTMLpage.py file somewhere in your path.
   
   *** Name the link "HTMLpage" (without the ".py" extension.)
       IT IS IMPERATIVE THAT YOU MAKE THIS LINK!
    
    
    
3) Could it be easier than above? Well, yes. If you don't have 
   the required dependencies. Python, GTK and pyGTK are not 
   necessary to run the binary package. Aspell is NOT included, 
   but as stated below it is optional.
     As with the source, put the HTMLpage folder wherever you 
   wish and symlink from the "HTMLpage" file to somewhere in 
   your path.
 
   *** Name the link "HTMLpage" (without the ".py" extension.)
       IT IS IMPERATIVE THAT YOU MAKE THIS LINK!
