/*
 * zlib — general-purpose compression library.
 *
 * The foundation of the dependency tree: nearly everything downstream
 * (openssl, curl, postgresql, nginx) links against libz.  Autotools-style
 * build: ./configure, make, make check, make DESTDIR install.
 *
 * DEPENDENCIES
 * ============
 * Runtime: none.  Build-time: a C toolchain (clang/gcc).
 *
 * NOTE: install goes into ${destdir} exclusively — kappa moves that tree
 * into the store.  Never point zlib's install at ${prefix} directly.
