Summary description: Mathematical sets with correctly scaled braces and separator
Announcement text: ------------------------------------------------------------------------
setbuilder is a new package providing smart set-builder notation: \set{x \given x > 0} typesets the braces and the separator bar with correct spacing, offers automatic (\set*) and fixed (\set[\Big]) scaling of both braces and separator, a "colon" style option, and a synonym= option for name-conflict-free usage.
