Lowercase naming requirement for systems?

[Robert Dodier]

Hi,

The ASDF manual says that the name of a system is a lowercase string.
Is that actually a requirement?

I was trying to create an .asd system which has a name with mixed
upper- and lowercase characters and the system is stored in a file of
the same name on a case-sensitive file system (Linux). But I get
"Component Foo not found" for that. If I change the name of the system
and the name of the file to lowercase, the system is found.

For the record, I've pasted the would-be mixed-case named system
below. It contains stuff that will make it generally unloadable since
you don't have my maxima-file hackery. If it turns out we need to go
into this in more detail, I will devise a more minimal example. But
first maybe someone can say what the name requirement is.

best,

Robert Dodier
