title: Install Section of rpm package
body: <p>I am naive on creating RPM packages.</p>
  
  <p>I want to know the meaning of below command:</p>
  
  <pre><code>BuildRoot: %{_tmppath}/build-%{name}-%{version}
  
        %install
        rm -rf "%{buildroot}"
        install -m 0755 -d "%{buildroot}%{_prefix}"
         %__install -D -m0644 "%{SOURCE0}" "%{buildroot}%{_prefix}/ROOT.war"
  
  %files
  %dir %{_prefix}
  %{_prefix}/ROOT.war
  </code></pre>
