+test-pkg: test-build a package against various toolchains and architectures
+
+The supplied config snippet is appended to each toolchain config, the
+resulting configuration is checked to ensure it still contains all options
+specified in the snippet; if any is missing, the build is skipped, on the
+assumption that the package under test requires a toolchain or architecture
+feature that is missing.
+
+In case failures are noticed, you can fix the package and just re-run the
+same command again; it will re-run the test where it failed. If you did
+specify a package (with -p), the package build dir will be removed first.
+
+The list of toolchains is retrieved from the Buildroot autobuilders, available
+at ${TOOLCHAINS_URL}.
+
+Options:
+
+ -h, --help
+ Print this help.
+
+ -c CFG, --config-snippet CFG
+ Use the CFG file as the source for the config snippet. This file
+ should contain all the config options required to build a package.
+
+ -d DIR, --build-dir DIR
+ Do the builds in directory DIR, one sub-dir per toolchain.
+
+ -p PKG, --package PKG
+ Test-build the package PKG, by running 'make PKG'; if not specified,
+ just runs 'make'.
+
+ -r N, --random N
+ Limit the tests to the N randomly selected toolchains, instead of
+ building with all toolchains.
+
+Example:
+
+ Testing libcec would require a config snippet that contains:
+ BR2_PACKAGE_LIBCEC=y
+
+ Testing libcurl with openSSL support would require a snippet such as:
+ BR2_PACKAGE_OPENSSL=y
+ BR2_PACKAGE_LIBCURL=y
