That sounds good - although I'd suggest the group's name might be a
valid alternative - then an underscore or hyphen, and the tool specific
ID which would typically be based on the name of the tool being wrapped.
If it were up to me I'd go further and recommend a restricted set of
characters (e.g. Alphanumeric and one of hyphen and underscore),
with the additional recommendation that the tool's XML filename
follows suit. e.g. signalp.xml with ID peterjc-signalp
Obviously we'd have to have a "grandfather clause" exemption for
all tools to date because changing their ID would break saved
As an aside, I regret including the word "wrapper" in the NCBI
BLAST+ wrappers since most Galaxy tools are just wrappers
around existing tools, but it's done now.
