-# Instructions:
-#
-# 1. Place your files into system folder (delete the placeholder file)
-# 2. Fill in your module's info into module.prop
-# 3. Configure and implement callbacks in this file
-# 4. If you need boot scripts, add them into common/post-fs-data.sh or common/service.sh
-# 5. Add your additional or modified system properties into common/system.prop
-#
-##########################################################################################
-
-##########################################################################################
-# Config Flags
-##########################################################################################
-
-# Set to true if you do *NOT* want Magisk to mount
-# any files for you. Most modules would NOT want
-# to set this flag to true
-SKIPMOUNT=false
-

-#
-# Function Callbacks
-#
-# The following functions will be called by the installation framework.
-# You do not have the ability to modify update-binary, the only way you can customize
-# installation is through implementing these functions.
-#
-# When running your callbacks, the installation framework will make sure the Magisk
-# internal busybox path is *PREPENDED* to PATH, so all common commands shall exist.
-# Also, it will make sure /data, /system, and /vendor is properly mounted.
-#
-##########################################################################################
-##########################################################################################
-#
-# The installation framework will export some variables and functions.
-# You should use these variables and functions for installation.
-#
-# ! DO NOT use any Magisk internal paths as those are NOT public API.
-# ! DO NOT use other functions in util_functions.sh as they are NOT public API.
-# ! Non public APIs are not guranteed to maintain compatibility between releases.
-#
-# Available variables:
-#
-# MAGISK_VER (string): the version string of current installed Magisk
-# MAGISK_VER_CODE (int): the version code of current installed Magisk
-# BOOTMODE (bool): true if the module is currently installing in Magisk Manager
-# MODPATH (path): the path where your module files should be installed
-# TMPDIR (path): a place where you can temporarily store files
-# ZIPFILE (path): your module's installation zip
-# ARCH (string): the architecture of the device. Value is either arm, arm64, x86, or x64
-# IS64BIT (bool): true if $ARCH is either arm64 or x64
-# API (int): the API level (Android version) of the device
-#
-# Availible functions:
-#
-# ui_print <msg>
-#     print <msg> to console
-#     Avoid using 'echo' as it will not display in custom recovery's console
-#
-# abort <msg>
-#     print error message <msg> to console and terminate installation
-#     Avoid using 'exit' as it will skip the termination cleanup steps
-#
-# set_perm <target> <owner> <group> <permission> [context]
-#     if [context] is empty, it will default to "u:object_r:system_file:s0"
-#     this function is a shorthand for the following commands
-#       chown owner.group target
-#       chmod permission target
-#       chcon context target
-#
-# set_perm_recursive <directory> <owner> <group> <dirpermission> <filepermission> [context]
-#     if [context] is empty, it will default to "u:object_r:system_file:s0"
-#     for all files in <directory>, it will call:
-#       set_perm file owner group filepermission context
-#     for all directories in <directory> (including itself), it will call:
-#       set_perm dir owner group dirpermission context
