### size_compare - compare size of OpenWrt packages against upstream
|
|
###
|
|
### The script compares locally compiled package with the package indexes
|
|
### available upstream. This way the storage impact of optimizations or
|
|
### feature modifications is easy to see.
|
|
###
|
|
### If no environmental variables are set the script reads the current
|
|
### .config file. The evaluated env variables are the following:
|
|
###
|
|
### TARGET SUBTARGET ARCH PACKAGES BIN_DIR BASE_URL CHECK_INSTALLED
|
|
###
|
|
### Usage:
|
|
### ./scripts/size_compare.sh
|
|
###
|
|
### Options:
|
|
### -p --package-size Check IPK package size and not installed size
|
|
### -h --help This message
