Hi Julien,

Thanks for the patches.  Just a few comments below:

In a few of the later patches, you declared 'home-page' before 'source'
so that it could be used in the uri.  That seams reasonable to me.  Did
you want to do that in all these patches?

How about some more widely meaningful, like: "Read and write JSON
data"?  IDK, see section 6.7.5 in the manual.

Similarly, I think we can leave out reference to the RFC in the
synopsis, since its in the description already.  "URI/URL parsing
library" seems enough.

Since this is a tool/application in its own right, rather than a
library, I think this package could be named "optcomp".  This would be
in line with other packages like "starman", "scons", "behave",
"snakemake", etc.

Remove the tab and align with spaces to '#:' on previous line.

Maybe: "Optional compilation for Ocaml"?

This patch is missing.

Does setting the "SHELL" environment variable work instead?

Is passing '#:configure-flags' not enough?

Is there some sort of configuration flag that can be used to install
these library into the right place?

Is this package to avoid having to build the entire piqi tool?

I think we'd rather leave the acronym out of the synopsis, and place it
in the description instead.

I think we can name this packages "ocaml-graph".  Similar to python
modules whose names begins with "python".

Synopses should not start with 'A'.  'guix lint' will warn about this.

> +    (description "A generic graph library for OCaml.")

Rather: "OCamlgraph is a generic graph library for OCaml."

Too bad this is so different from GNU's DESTDIR semantics...

Again, I wonder if setting "SHELL" in the environment would suffice.
It would be less heavy-handed.

Could you put these flags in '#:configure-flags' instead?

A short comment on why this phase is needed might be useful.

Maybe our ocaml-build-system should be defining SHELL and CONFIG_SHELL
in the flags passed to configure, like gnu-build-system does.  Or does
that not work for some ocaml projects?


Otherwise looks good to me.

Sorry for long reply and all the questions,
