 ===== Obtaining multilib packages =====
-You can download a set of multilib-enabled packages and scripts from my web site: http://slackware.com/~alien/multilib/ .
+You can download a set of multilib-enabled packages and scripts from my web site: http://connie.slackware.com/~alien/multilib/ .
-The packages are accompanied by sources and SlackBuild scripts, plus several README files (this Wiki article is based on one of these READMEs). The //only// required downloads are the binary packages in //<slackware_release_number>// directory below the toplevel directory. The rest is available for educational purposes.
+Apart from several README files (this Wiki article is based on one of these READMEs), you will find one subdirectory for every 64-bit Slackware release below the toplevel directory "//multilib//". There is another directory called "source". The "//source//" directory contains package sources and SlackBuild scripts.\\ The stuff that you are really interested in - the binary packages - is available in the //<slackware_release_number>// directory below the toplevel directory. Every such directory also contains a "//slackware64-compat32//" subdirectory where you will find an essential set of converted 32-bit Slackware packages, ready for installing on your 64-bit Slackware.
+<note tip>In order to keep up to date, I advise you to keep an eye on the [[http://connie.slackware.com/~alien/multilib/ChangeLog.txt | ChangeLog]] I keep for my multilib packages. Usually, I will have //updated glibc and gcc// packages available within a day after Slackware has updates to gcc and glibc. Also check out [[#rd_party_support_tools | compat32pkg]] by Sėbastien Ballet which automates this process, similar to slackpkg.</note>

 There is one additional package that you install using the "installpkg" program:
@@ Line 114: / Line 157: @@
 A little bit of extra care is required so that unnecessary/unwanted files are stripped from the 32bit packages before you install them. What you need, is a 32bit package that does not conflict with whatever is already present in 64bit Slackware. Hence the name "32bit compatibility package".
-I decided that it would be a waste of download bandwidth if I created 32bit compatibility versions of Slackware packages myself. After all, you have probably bought the Slackware 13.0 DVD so you already possess both 64bit and 32bit versions of Slackware... or else the 32bit Slackware tree is available for free download of course ;-)

 Instead, I wrote a few scripts (parts of the script code were written by Fred Emmott of [[http://slamd64.com/ | Slamd64]] fame) and wrapped these into a "//compat32-tools//" package. Their purpose is to let you extract the content from any 32bit Slackware package and use that to create a new package  which you can safely install on your 64bit Slackware.

 </code> This action will result in about 60 MB of new packages which you will find inside the newly created directory ''~/compat32'' (the directory's name is arbitrary of course, I chose it for the sake of this example). These packages comprise the 32bit component of your multilib Slackware64 system.\\ They should be installed using "''installpkg''", and they give you a pretty complete 32-bit compatibility layer on top of Slackware64: <code>

 ===== Caveats =====
-After installing the "''-compat32''" packages, you may have to re-install your binary //Nvidia// or //Ati// video X.Org drivers. These driver packages contain both 64bit and 32bit libraries to be maximally useful on a 64bit multilib OS. If you installed the driver files for both architectures, the "''mesa-compat32''" package will overwrite some of the 32bit library files.

 ===== Packages converted by massconvert32.sh =====
-This is the list of packages that is converted into "//-compat32//" versions by the ''massconvert32.sh'' script. Note that some of these packages are not part of Slackware 13.0, they were added in Slackware 13.1 so they will produce a "//*** FAIL: package 'package_name' was not found!//" message when you run the script. Don't worry about that.
