1.1 veillard 40: <p>\n\
1.7 veillard 41: The goals of rpm2html are also to identify the dependencies between\n\
42: various packages and to find the package(s) providing the resources\n\
43: needed to install a given package. Every package is analyzed to\n\
44: retrieve its dependencies and the resources it offers. These\n\
45: relationships are expressed using hyperlinks in the generated\n\
46: pages. Finding the package providing the resource you need is just a\n\
47: matter of a few clicks!</p>\n\
1.1 veillard 48: <p>\n\
1.7 veillard 49: The ultimate commodity is ensured by indexing this set of pages,\n\
50: allowing the user to find instantaneously the package(s) providing any\n\
51: given functionality (as long as the package maintainer has properly\n\
1.11 veillard 52: commented the RPM).</p>\n\
