you wish to use the .deb packages to install Oolite, you will need to
download 2 files. You will need the oolite-data.deb and,
on the processor(s) in your computer, either the i386.deb or
accordingly. To install, double-click on the
downloaded amd or i386 deb file icon and follow the on-screen
directions. If you wish to install via the console, most likely
you don't need any directions from me anyway...
To ensure that the installer you have downloaded is genuine and that your download has not been corrupted, it is STRONGLY RECOMMENDED that you check that the MD5 sum of the file you downloaded matches the appropriate MD5. You should download the MD5 file for your operating system and compare them using the following tools.
For Windows users, I suggest using the excellent little freeware program HashOnClick. To use it you simply copy the text in the MD5 file to the clipboard, then right-click the installer file and choose "Calculate Hash Value > MD5" from the context-menu. HashOnClick will then report if the programs MD5 sum matches the one in the clipboard. There are a number of other freeware MD5-sum calculating programs available for Windows if you prefer to choose your own.
Linux users should save the MD5 file in the same directory as the downloaded installer, then open a Terminal, cd to the directory where the files are located and type "md5sum oolite-1.73.4[rest-of-filename] ; cat oolite-1.73.4[rest-of-filename].md5 " (without the quotes) to check the integrity of the installer package. Alternatively, should you prefer a GUI tool to check the MD5 sum, you could try JSummer.
Macintosh OS X users should save the MD5 file in the same directory as the downloaded installer, then open a Terminal, cd to the directory where the files are located and type "md5 -c oolite-1.73.4-test-mac-full.zip.md5" (without the quotes) to check the integrity of the installer zip-file.
