-#
-# This script builds many
diff erent flavors of the LLVM ecosystem. It
-# will build LLVM, Clang and dragonegg as well as run tests on them.
-# This script is convenient to use to check builds and tests before
-# committing changes to the upstream repository
-#
-# A typical source setup uses three trees and looks like this:
-#
-# official
-# dragonegg
-# llvm
-# tools
-# clang
-# staging
-# dragonegg
-# llvm
-# tools
-# clang
-# commit
-# dragonegg
-# llvm
-# tools
-# clang
-#
-# In a typical workflow, the "official" tree always contains unchanged
-# sources from the main LLVM project repositories. The "staging" tree
-# is where local work is done. A set of changes resides there waiting
-# to be moved upstream. The "commit" tree is where changes from
-# "staging" make their way upstream. Individual incremental changes
-# from "staging" are applied to "commit" and committed upstream after
-# a successful build and test run. A successful build is one in which
-# testing results in no more failures than seen in the testing of the
-# "official" tree.
-#
-# A build may be invoked as such:
-#
-# llvmbuild --src=~/llvm/commit --src=~/llvm/staging --src=~/llvm/official
-# --build=debug --build=release --build=paranoid
-# --prefix=/home/greened/install --builddir=/home/greened/build
-#
-# This will build the LLVM ecosystem, including LLVM, Clangand
-# dragonegg, putting build results in ~/build and installing tools in
-# ~/install. llvm-compilers-check creates separate build and install
-# directories for each source/build flavor. In the above example,
-# llvmbuild will build debug, release and paranoid (debug+checks)
-# flavors from each source tree (official, staging and commit) for a
-# total of nine builds. All builds will be run in parallel.
-#
-# The user may control parallelism via the --jobs and --threads
-# switches. --jobs tells llvm-compilers-check the maximum total
-# number of builds to activate in parallel. The user may think of it
-# as equivalent to the GNU make -j switch. --threads tells
-# llvm-compilers-check how many worker threads to use to accomplish
-# those builds. If --threads is less than --jobs, --threads workers
-# will be launched and each one will pick a source/flavor combination
-# to build. Then llvm-compilers-check will invoke GNU make with -j
-# (--jobs / --threads) to use up the remaining job capacity. Once a
-# worker is finished with a build, it will pick another combination
-# off the list and start building it.
