 * Build and install mrustc (from slackbuilds.org). You now have a fully
   functional rust 1.19.0.
-* Now build for rust 1.20.0, 1.21.0, 1.22.1, 1.23.0, 1.24.1, 1.25.0, and finally
-  1.26.2.

 This slackbuild is currently compatible with each of those versions.
 Since we are building completely from source, you only need the source

     VERSION=1.24.1 FULL_BOOTSTRAP=no  LOCAL_BOOTSTRAP=yes ./rust.SlackBuild
     VERSION=1.25.0 FULL_BOOTSTRAP=no  LOCAL_BOOTSTRAP=yes ./rust.SlackBuild

+    VERSION=1.27.2 FULL_BOOTSTRAP=no  LOCAL_BOOTSTRAP=yes ./rust.SlackBuild
 
 You might prefer to do a full bootstrap for 1.20.0, which is what mrustc's own
 bootstrap script suggests. The versions after that do not need a full bootstrap.
