1.7 veillard 33: <strong>rpm2html</strong> automatically generate Web pages describing a set of\n\

35: <p>\n\
1.7 veillard 36: The goals of rpm2html are also to identify the dependencies between\n\
37: various packages and to find the package(s) providing the resources\n\
38: needed to install a given package. Every package is analyzed to\n\
39: retrieve its dependencies and the resources it offers. These\n\
40: relationships are expressed using hyperlinks in the generated\n\
41: pages. Finding the package providing the resource you need is just a\n\
42: matter of a few clicks!</p>\n\
1.1 veillard 43: <p>\n\
1.7 veillard 44: The ultimate commodity is ensured by indexing this set of pages,\n\
45: allowing the user to find instantaneously the package(s) providing any\n\
46: given functionality (as long as the package maintainer has properly\n\
47: commented the RPM).</p>\n",
