genrandconfig is used by the Buildroot autobuilders to generate semi-random configurations that we build test. As part of this, we use "make randpackageconfig" to randomize the selection of packages, together with a KCONFIG_PROBABILITY value, which indicates the probabibility for each option to be enabled. This probability is itself randomized, between 1% and 30% for every build. However, with our increasing number of packages (over 2900), when we use a 30% probability for options to be enabled, it means a *lot* of options are enabled, causing very large configurations to be tested. These configurations are not very realistic, and they take ages to build on our autobuilders: we have builds that take 4, 5 or even 7 hours to build. In order to test a larger number of configurations and therefore a larger variety of configurations, this commit reduces the maximum probability to 20%.

This directory contains various useful scripts and tools for working with Buildroot. You need not add this directory in your PATH to use any of those tools, but you may do so if you want. brmake a script that can be run instead of make, that prepends the date in front of each line, redirects all of the build output to a file ("'br.log' in the current directory), and just outputs the Buildroot messages (those lines starting with >>>) on stdout. Do not run this script for interactive configuration (e.g. menuconfig) or on an unconfigured directory. The output is redirected so you will see nothing. check-package a script that checks the coding style of a package's Config.in and .mk files, and also tests them for various types of typoes. genrandconfig a script that generates a random configuration, used by the autobuilders (http://autobuild.buildroot.org). It selects a random toolchain from support/config-fragments/autobuild and randomly selects packages to build. get-developpers a script to return the list of people interested in a specific part of Buildroot, so they can be Cc:ed on a mail. Accepts a patch as input, a package name or and architecture name. scancpan a script to create a Buildroot package by scanning a CPAN module description. scanpypi a script to create a Buildroot package by scanning a PyPI package description. size-stats-compare a script to compare the rootfs size between two different Buildroot configurations. This can be used to identify the size impact of a specific option, of a set of specific options, or of an update to a newer Buildroot version... test-pkg a script that tests a specific package against a set of various toolchains, with the goal to detect toolchain-related dependencies (wchar, threads...)
