Is there a lout package repository?

Hi lout-users,

i used Latex in the past and now want to try something new.
In Latex there are packages, which provide syntax and symbols for
chemistry, cryptography and so on.
Are there such packages in lout?
Are there package distributions or reprositoires like CTAN?

And last but not least can you recommend any howtos/texts/documentation
when it comes to writing your own code?
