+== Use variables
+
+You can alter the result of the build process using environment variables
+without touching the FrugalBuild itself. The `git` package is a good example.
+Using
+
+-----------------------------------
+$ USE_DEVEL=y sudo makepkg [<options>]
+-----------------------------------
+
+for that package results in a build of git's development version. Here is what
+you need if you want so for your package:
+
+----
+# set the variable to false by default
+USE_DEVEL=${USE_DEVEL:-"n"}
+
+(...)
+
+# these commands will be evaluated only in case USE_DEVEL is set to true
+if Fuse $USE_DEVEL; then
+ _F_scm_type="git"
+ _F_scm_url="git://git.kernel.org/pub/scm/git/git.git"
+ Finclude scm
+fi
+----
+
In the next section we will see an example for a simple FrugalBuild script.
