Your main GitHub page at https://github.com/tskit-dev/pyslim writes pyslim as "pySLiM". I haven't seen that mixed-case spelling of it anywhere else, so it kinda looks like a bug to me – maybe you initially thought of naming it that and then changed your mind? Anyhow, seems like it ought to be fixed, unless you really intend that to be how it is written – in which case many, many other places need to be changed. ;->
