    While the .spec file is text in nature, it isn't a set of instructions as
    you would normally think of one. Instead, it's actually a set of
    instructions to RPM on how to build and package the particular piece of
    software (configure, make, make check, make install.) So, by looking at
    the .spec file for a particular Red Hat supplied package, you can not only
    see exactly what steps Red Hat used in order to compile a particular set of
    binaries, but you can also make changes to the source code for yourself,
    then utilize the Red Hat supplied .spec file in order to build a new
    package, with your changes incorporated.

    As for what to use to inspect the SRPM, there are a couple of options.
    First, you can just install the SRPM package, which will put the source
    code and any patches in the /usr/src/redhat/SOURCES directory and the SPEC
    file in the /usr/src/redhat/SPECS directory. Then you can use your
    favorite text viewer/editor to view the .spec file. Or you can install a
    tool such as "mc" which understands RPMs and can pull them apart and
    display the internals without having to actually install the package
    itself.
