+Here are some general guidelines for writing spec files.
+
+* RPM does not allow you to use dashes in version or release
+ numbers. Use dots, or nothing.
+
+* Most versions of RPM poorly handle version and release numbers that
+ do not begin with a number. Start your version and release number with
+ at least one number. Append as many minor numbers as you want, but
+ leave alphabetic characters at the end of the string.
+
+* Always define BuildRoot based in %{_tmppath}.
+
+* In the %install step, always install files based in $RPM_BUILD_DIR.
+
+* Don't be overly restrictive with Requires or BuildRequires tags. RPM
+ is already pretty smart about analyzing your package for necessary
+ dependencies. Usually, you only need to specify Requires tags to make
+ sure a set of packages get installed in the right order (if there is
+ one). Otherwise, it's likely your users will end up in awful
+ situations requiring manual bootstrap.
+
+Here are some specific guidelines for writing spec files for this setup.
+
+* Explicitly %define %{name}, %{version}, %{release}. You should do this
+ anyway to support older versions of RPM. This Makefile does not
+ implicitly define these variables (based on the Name:, Version:, and
+ Release: tags) as RPM does.
+
+* Run cvsps(1) manually on your repository, and synchronize the PatchSet
+ numbers with any Patch: tags in your spec file that you would like
+ explicitly named.
+
+* This Makefile assumes that the build directory (as specified by the -n
+ option to %setup, or the RPM default %{name}-%{version}) is the
+ basename of the Source file (i.e. without .tar[.gz|.bz2]).
+
+* Add %{?date:.%{date}} to your %{release} tag. When executed, this
+ Makefile will define the variable to be the current date in YY.MM.DD
+ form. This will help automated nightly upgrades. Tagged releases
+ will not define this variable.
+
+* Unless you have a very good reason not to, use the following tags:
