 INSTALL
 -------

 1. If a previous THttpScan package is already installed, 
   remove it first:

   - Components | Install Packages,

   - click on "DataStead THttpScan",

   - click "Remove",

   - click "Yes",

   - click "Ok",

   - search for "HttpScan.*" and "THtScan.*" files in your Borland 
     directories and delete them, to be certain that old units will
     not remain in the search paths (causing later raw errors). 


 2. Install the current package:

    - unzip the archive in a folder of your choice,

    - according to your Delphi or C++Builder version, copy all 
      the Delphi\*.* or CBuilder\*.* archive files to 
      the Borland\Delphi\Imports or \Borland\CBuilder\Imports directory,

    - run Delphi or C++Builder,

    - select Component | Install packages,

    - press the "Add" button,

    - locate the THtScan.bpl file in the Imports directory and select it,

    - select Open,

    - select Ok,

    - check the DataStead tab in the right of the component palette. 
      The THttpScan object should have been added.





 INSTALL TROUBLESHOOTING
 =======================


 ERROR "THtScan.??? file not found" when compiling:
 -------------------------------------------------

 - go to Tools | Environment Options | Library, and check that there is ;$(DELPHI)\Imports (with Delphi) 
   or ;$(BCB)\Imports (with C++Builder) in the Library path, otherwise add it at the end of the edit field.  

 - go to Project | Options | Packages, check "Build with runtime package", go to the end of the 
   packages edit field, remove ";THtScan", and then uncheck "Build with runtime package". 


 ZIP PACKAGE:
 -----------

 When unzipping the package, the unzip tool must re-create all the the package's subdirectories. 
 By using WinZip, be sure to enable "use folder names" before unzipping.


 DELPHI 6 TRIAL: 
 --------------

 The trial version of Delphi 6 comes with a different DCU format than the 
 real one. You can't use THttpScan or other third party components in the trial, otherwise
 you will get the following error when trying to build the project:
 Access violation at address nnnnnn in module dcc60.dll read of address nnnnn.
