+# DarkForge Linux — Phase 0, Chapter 7: Zlib (Chroot)
+# ============================================================================
+# Purpose:  Build zlib inside the chroot. The binutils linker (ld) from pass 2
+#           was built with zlib support and dynamically links against libz.so.1.
+#           Without zlib installed, ld fails with:
+#             "error while loading shared libraries: libz.so.1"
+#           This must be the FIRST thing built in the chroot, before any
+#           package that needs to link (i.e., everything).
+# Inputs:   /sources/zlib-1.3.2.tar.xz
+# Outputs:  /usr/lib/libz.so.1
+# Assumes:  Running inside chroot
+# ============================================================================
