# * What's this?
#  	This is a makefile to generate a gfw-free Firefox portable release powered
#  	by shadowsocks
#
# * How to use it?
#   To generate the release, you will need:
#   - An available ShadowSocks server
#   - A Firefox portable base package downloaded from
#       http://portableapps.com/apps/internet/firefox_portable
#
#   1. Writing the shadowsocks server info into config.js
#   2. Install portable Firefox
#   3. Edit following makefile, mainly for:
#       - SS_BIN, binary shadowsocks client, go version is recommended
#       - FF_PORTABLE_BASE if its not the FirefoxPortable folder beside Makefile
#       - SS_CONFIG, shadowsocks configuration file
#   4. Run `make`
#   5. Optionally, run `make prune` to remove files unnecessary to end-users
#   6. Pack the FF_PORTABLE_BASE folder and release it as you like
#

SS_BIN = $(GOPATH)/bin/shadowsocks-local.exe
SS_CONFIG = config.json
