Front-end to ocamlfind that adds a few new commands
Description
The command not-ocamlfind is a pass-thru to ocamlfind, but adds three new
commands: preprocess, reinstall-if-diff and package-graph.
- reinstall-if-diff does what it says on the label: only reinstalls (remove
then install) if the file-content of the package has changed.
- preprocess produces the source and does not attempt to compile it; as an
added benefit, it prints (to stderr) the commands it executed to produce
that source. So you can use this for debugging multi-stage PPX rewriter
sequences.
- package-graph outputs a graph in the format accepted by the dot command of
graphviz. By default you get the package-dependency graph, with sizes of
the archives for each packages as part of the node-label. If you add
`-dominator-from <node>`, it will compute the dominator-tree from that node,
and if you add `-xdot`, it will automatically invoke xdot on the graph.
