+      Apache Ant is a Java-based build tool.  In theory, it is kind of like
+      Make, but without Make's wrinkles.
+
+      Why another build tool when there is already make, gnumake, nmake, jam,
+      and others? Because all those tools have limitations that Ant's
+      original author couldn't live with when developing software across
+      multiple platforms.  Make-like tools are inherently shell-based -- they
+      evaluate a set of dependencies, then execute commands not unlike what
+      you would issue in a shell.  This means that you can easily extend
+      these tools by using or writing any program for the OS that you are
+      working on.  However, this also means that you limit yourself to the
+      OS, or at least the OS type such as Unix, that you are working on.
+
+      Ant is different.  Instead of a model where it is extended with
+      shell-based commands, Ant is extended using Java classes.  Instead of
+      writing shell commands, the configuration files are XML-based, calling
+      out a target tree where various tasks get executed.  Each task is run
+      by an object that implements a particular Task interface.

+From https://github.com/grpc/grpc/commit/57586a1ca7f17b1916aed3dea4ff8de872dbf853
+From: Benjamin Peterson <benjamin@dropbox.com>
+Date: Fri, 3 May 2019 08:11:00 -0700
+Subject: [PATCH] Rename gettid() functions.
+
+glibc 2.30 will declare its own gettid; see https://sourceware.org/git/?p=glibc.git;a=commit;h=1d0fc213824eaa2a8f8c4385daaa698ee8fb7c92. Rename the grpc versions to avoid naming conflicts.

+Date: Fri, 3 May 2019 08:11:00 -0700
+Subject: [PATCH] Rename gettid() functions.
+
+glibc 2.30 will declare its own gettid; see https://sourceware.org/git/?p=glibc.git;a=commit;h=1d0fc213824eaa2a8f8c4385daaa698ee8fb7c92. Rename the grpc versions to avoid naming conflicts.

+Date: Fri, 3 May 2019 08:11:00 -0700
+Subject: [PATCH] Rename gettid() functions.
+
+glibc 2.30 will declare its own gettid; see https://sourceware.org/git/?p=glibc.git;a=commit;h=1d0fc213824eaa2a8f8c4385daaa698ee8fb7c92. Rename the grpc versions to avoid naming conflicts.

+Subject: [PATCH] Trim last argument to gcc if empty, on Darwin
+
+On Darwin, the last argument to GCC is coming up as an empty string.
+This is breaking the build of proto_library targets. However, I was not
+able to reproduce with the example cpp project[0].
+
+This commit removes the last argument if it's an empty string. This is
+not a problem on Linux.

+* posixos.c (set_blocking): Set blocking on a file descriptor.
+(jobserver_setup): Set non-blocking on the jobserver read side.
+(jobserver_parse_auth): Ditto.
+(jobserver_acquire_all): Set blocking to avoid a busy-wait loop.
+(jobserver_acquire): If the non-blocking read() returns without
+taking a token then try again.

+%%% ---------------------------------------------------------------------------
+%%% @doc
+%%% The purpose of this command is to prepare a rebar3 project so that
+%%% rebar3 understands that the dependencies are all already
+%%% installed. If you want a hygienic build on nix then you must run
+%%% this command before running rebar3. I suggest that you add a
+%%% `Makefile` to your project and have the bootstrap command be a
+%%% dependency of the build commands. See the nix documentation for
+%%% more information.
+%%%
+%%% This command designed to have as few dependencies as possible so
+%%% that it can be a dependency of root level packages like rebar3. To
+%%% that end it does many things in a fairly simplistic way. That is
+%%% by design.
+%%%
+%%% ### Assumptions
+%%%
+%%% This command makes the following assumptions:
+%%%
+%%% * It is run in a nix-shell or nix-build environment
+%%% * that all dependencies have been added to the ERL_LIBS
+%%%   Environment Variable

+      Tup is a file-based build system for Linux, OSX, and Windows. It inputs a list
+      of file changes and a directed acyclic graph (DAG), then processes the DAG to
+      execute the appropriate commands required to update dependent files. Updates are
+      performed with very little overhead since tup implements powerful build
+      algorithms to avoid doing unnecessary work. This means you can stay focused on
+      your project rather than on your build system.
