	# Since we build zsh non-dynamically (since dynamic loading doesn't work on Android when enabled),
	# we need to explicitly enable the additional modules we want.
	# - The files module is needed by `compinstall` (https://github.com/termux/termux-packages/issues/61).
	# - The regex module seems to be used by several extensions.
	# - The curses, socket and zprof modules was desired by BrainDamage on IRC (#termux).
	# - The deltochar and mathfunc modules is used by grml-zshrc (https://github.com/termux/termux-packages/issues/494).
	# - The system module is needed by zplug (https://github.com/termux/termux-packages/issues/659).
	# - The zpty module is needed by zsh-async (https://github.com/termux/termux-packages/issues/672).
	# - The stat module is needed by zui (https://github.com/termux/termux-packages/issues/2829).
	# - The mapfile module was requested in https://github.com/termux/termux-packages/issues/3116.
	# - The zselect module is used by multiple plugins (https://github.com/termux/termux-packages/issues/4939)
	# - The param_private module was requested in https://github.com/termux/termux-packages/issues/7391.
	# - The cap module was requested in https://github.com/termux/termux-packages/issues/3102.
