This is the contents of /usr/doc/rpm*/macros only nicely
formatted.  Macros in RPM are used in the spec file for building RPMs
only (ie this is not an end user item).
RPM 2.3.9 introduces simple spec file macros.  The macros can do
straight text substitution only.  Macros can be used anywhere in
a spec file, and in ``included file lists'' (those read in using
%files -f <file>).
4.1 Defining a Macro 
To define a macro use:
%define <name> <expansion>
All whitespace surrounding <expansion> is removed.  Name may be composed
of alphanumeric characters, and the character `_' (the underscore).  Macro expansion is
performed on 
<expansion> so that <expansion> my reference other macros
that have already been defined.
4.2 Using a Macro 
To use a macro, write:
%<name>
or
%{<name>}
The latter allows you to place the expansion adjacent to other text.
4.3 Predefined Macros 
The following macros are defined as the values they reference are
specified in the spec file:
