+This tool is based on xpdf (currently 1.01). It uses the (mostly unmodified -

 Changes to xpdf:
  - xpdf calculates nearly everything with doubles. Since ARMs are not equipped
    with a FPU, all doubles have been replaced with a C++ class "fouble" (fixed
    double), which operates on 32bit integers with fixed point arithmetic.
    This gave a speedup of up to 800% for image rendering.

 Install:
- - xpdf-1.00
-   Get the tarball for xpdf, version 1.0, untar it and ./configure it.
-   (No special flags are needed for ./configure - it simply has to run)
-   
- - qpdf
-   Make sure your QPEDIR / TMAKEPATH variables are correctly !
- 
-   cd into the xpdf directory (xpdf-1.00) and untar the qpdf tarball. This 
-   should create a subdirectory qpdf.
-   cd into this directory and start the script "./setup-qpdf". This 
-   incorporates the above mentioned patches into xpdf.
-   
-   Now do a make.

-   Copy the files qpdf, qpdf_icon.png and qpdf.desktop to the appropriate

    old format.
    
-   If you do not have a working uncompress installed on your iPaq, you can 
-   simply use the one in the contrib directory of the tarball (make uncompress 
-   a link to compress).
