-DASH is a POSIX-compliant implementation of /bin/sh that aims to be as 
-small as possible.  It does this without sacrificing speed where possible. 
-In fact, it is significantly faster than bash (the GNU Bourne-Again SHell) 
-for most tasks.
-
-To patch in fixes from current git, add 'USE_GIT_PATCH=yes' to the command
-line when building, like this:
-
-# USE_GIT_PATCH=yes sh dash.Slackbuild
-
-or, if you use fakeroot to build:
-
-$ fakeroot env USE_GIT_PATCH=yes sh dash.SlackBuild
