1.7 veillard 40: The goals of rpm2html are also to identify the dependencies between\n\
41: various packages and to find the package(s) providing the resources\n\
42: needed to install a given package. Every package is analyzed to\n\
43: retrieve its dependencies and the resources it offers. These\n\
44: relationships are expressed using hyperlinks in the generated\n\
45: pages. Finding the package providing the resource you need is just a\n\
46: matter of a few clicks!</p>\n\
