# DarkForge Linux — Phase 0, Chapter 6: Ncurses
# ============================================================================
# Purpose:  Cross-compile the ncurses library (terminal handling). Required
#           by bash, many TUI programs, and the installer.
# Inputs:   ${LFS}/sources/ncurses-6.5.tar.gz
# Outputs:  ncurses libraries and tic utility in ${LFS}/usr/
# Assumes:  Cross-toolchain (Ch.5) complete
# Ref:      LFS 13.0 §6.3
# ============================================================================
