Got an email from a new user... he had read the README for the build he

Would it hurt to add some text to the HOWTO page explaining this? I
know it's pretty elementary stuff, but the HOWTO already details how to
extract a tarball and launch a shell script from the current directory,
which are also elementary tasks...
Proposed text to add to the end of "Step 2 - Read the README":
If the README mentions any options controlled by environment variables,
you can set these options now by running:
For instance, if the README says you can build against SDL 2.0 by setting
SDL2=yes in the environment, you would type:
If there are multiple options, you can use multiple export commands.
If you're unsure, don't set any variables here. In most cases, the
SlackBuild maintainer has made the default behaviour (no options) the
most common or most useful way to build the package.
...yes, it's possible (and "cleaner") to just say SDL2=yes
./whatever.SlackBuild in Step 4, but the way the howto is split up
into steps, it would make less sense for step 4 to effectively say "Oh,
by the way, you should have noticed if there were environment variable
options in step 2". So Step 2 has to mention them, since that's where
