NAME
       yum-builddep - install missing dependencies for building an RPM package

SYNOPSIS
       yum-builddep package

DESCRIPTION
       yum-builddep  is a program which installs the RPMs needed to build the specified package.  The source RPM for the specified package must be available in a Yum repository (which will be
       automatically enabled, if it is disabled) or it can be a local source RPM or a spec file.

EXAMPLES
       Download and install all the RPMs needed to build the kernel RPM:
              yum-builddep kernel

FILES
       As yum-builddep uses YUM libraries for retrieving all the information, it relies on YUM configuration for its default values like which repositories to use. Consult  YUM  documentation
       for details:

/etc/yum.conf
       /etc/yum/repos.d/
