1) Unzip RefalP.zip to an empty directory.

2) Call Cygwin and enter under it in this directory.

3) Run

    a) ./configure -prefix (path to cygnus/cygwin-b20/H-i586-cygwin32)

    For example:

    ./configure -prefix C:/Progra~1/Cygnus/cygwin-b20/H-i586-cygwin32

    Pay attention to the direction "/"!

    b) make

    c) make install-win

4) The directory with RefalP can be deleted.

5) To continue using Refal Plus without cygwin,

just add the directory C:\Program Files\Cygnus\cygwin-b20\H-i586-cygwin32\bin to the path,

which contains the following files: rfp.exe, rfpc.exe, rfpchk.exe, rfps.exe

and the cygwin1.dll library required for the compiled program to work

on Refal Plus.
