This file contains the following sections:
 - How to install?
 - How to check MD5 and SHA1 checksums.
 - About releases
   - SetupRCL-release-1.0.0b.msi
   - RCL-1.0.0b-source.zip


How to install?
==============
This procedure is tested on a Windows 7 64 bits machine.
1. Download the .msi file.
   Check the MD5 and/or SHA1 sums for the .msi file.
   (See 'About releases' for the correct MD5 and SHA1 checksums.)

2. Right click on the downloaded file and select properties. 
   If you see a security warning and a button [ Unlock ] then continue
   with step 3, else go to step 4.

3. You see a security warning:
   This file came from another computer and might be blocked to help
   protect this computer.

   This is just one of the protection steps made by Microsoft to help you
   fighting malicious downloads. If you really trust the .msi file (did
   you check the MD5 and/or SHA1 sums given in step 1?) then press the
   button [ Unlock ] and continue.

4. Double click on the .msi file and follow the on screen instructions to
   install RCL.

   
How to check MD5 and SHA1 checksums.
===================================
Any software creating or verifying the MD5 and/or SHA1 checksum should
do. If you do not have software for it then follow these steps. (Note:
this is just one of the possible sources for MD5 and SHA1 software, use
anyone you really trust.)

1. Navigate to "http://gnuwin32.sourceforge.net/packages.html"
2. Look for package 'CoreUtils' (This instruction used version 5.3.0)
3. Download the package by following the link 'Setup' or read more
   about the package by following the link 'CoreUtils', look for the line
   with 'Complete package, except sources' and follow the link 'Setup'.
   Note: in the second case you also find a MD5 value for the package.
4. Install the package, the default location for installation is:
   On 32 bit systems: "C:\Program Files\GnuWin32"
   On 64 bit systems: "C:\Program Files (x86)\GnuWin32"
   The commands are installed in the '.\bin' directory.
5. See that the commands are working by opening a command window and
   type:
   C:\Users\name>C:\Program Files (x86)\GnuWin32\bin\md5sum --help
   Usage: md5sum [OPTION] [FILE]...
     or:  md5sum [OPTION] --check [FILE]
   Print or check MD5 (128-bit) checksums.
   ...
   C:\Users\name>C:\Program Files (x86)\GnuWin32\bin\sha1sum --help
   Usage: sha1sum [OPTION] [FILE]...
     or:  sha1sum [OPTION] --check [FILE]
   Print or check SHA1 (160-bit) checksums.
   ...
6  Let the tools compare the MD5 and SHA1 checksums.
   Create a file with the checksums in it e.g.:
   (assuming that your downloaded file is in the same location as this file).
   Checksums.txt
   0b9484be7fabc76876b5d8e110e716ad *SetupRCL-release-1.0.0b.msi
   994631c7d92f964ef6a5b29be77eeb05bb80dbc4 *SetupRCL-release-1.0.0b.msi
   
   Run the commands and get an 'OK' message.
   C:\Users\name>C:\Program Files (x86)\GnuWin32\bin\md5sum --check Checksums.txt
   SetupRCL-release-1.0.0b.msi: OK
   C:\Users\name>C:\Program Files (x86)\GnuWin32\bin\sha1sum --check Checksums.txt
   SetupRCL-release-1.0.0b.msi: OK

   If you do not get an 'OK' then the file is not what you want due to
   unknown causes. It might be a corrupted download, a plain error in the
   checksum given to you to check for or a subversive action
   causing the MD5 and SHA1 values to mismatch. Don't trust the file,
   throw it away.
   To rule out a corruption while getting the file try to download it
   again and recheck. If the problem is persistent, please inform the
   maintainer(s) by sending in a notification.
