+Description:
+The gflags package contains a library that implements commandline
+flags processing. As such it's a replacement for getopt(). It has
+increased flexibility, including built-in support for C++ types like
+string, and the ability to define flags in the source file in which
+they're used.
+
+Local Modifications: None
+
+
+How to update platform configuration files:
+The gen/ directory contains pre-generated configuration header files.
+Historically, all operating systems and architectures have generated
+similar configurations except for Windows. This is why there's only
+posix and win directories below gen/.
+When rolling gflags to a newer version, it's a good idea to check if
+new configuration files needs to be generated as well.
+Do this by running cmake in the newly checked out version of
+gflags. Then diff the generated files with the ones below gen/.
+If you notice a diff, update the files with the updated ones.
+If you suspect platform dependend changes other than Windows, you'll
+have to checkout gflags on the other platforms as well and run
+cmake there too.

+// thread-safe: it is safe for multiple threads to call this routine
+//   (or, when referring to a class, methods of this class)
+//   concurrently.
+// thread-hostile: it is not safe for multiple threads to call this
+//   routine (or methods of this class) concurrently.  In gflags,
+//   most thread-hostile routines are intended to be called early in,
+//   or even before, main() -- that is, before threads are spawned.
+// thread-compatible: it is safe for multiple threads to read from
+//   this variable (when applied to variables), or to call const
+//   methods of this class (when applied to classes), as long as no
+//   other thread is writing to the variable or calling non-const
+//   methods of this class.

+// --------------------------------------------------------------------
+// Now come the command line flag declaration/definition macros that
+// will actually be used.  They're kind of hairy.  A major reason
+// for this is initialization: we want people to be able to access
+// variables in global constructors and have that not crash, even if
+// their global constructor runs before the global constructor here.
+// (Obviously, we can't guarantee the flags will have the correct
+// default value in that case, but at least accessing them is safe.)
+// The only way to do that is have flags point to a static buffer.
+// So we make one, using a union to ensure proper alignment, and
+// then use placement-new to actually set up the flag with the
+// correct default value.  In the same vein, we have to worry about
+// flag access in global destructors, so FlagRegisterer has to be
+// careful never to destroy the flag-values it constructs.
+//
+// Note that when we define a flag variable FLAGS_<name>, we also
+// preemptively define a junk variable, FLAGS_no<name>.  This is to
+// cause a link-time error if someone tries to define 2 flags with
+// names like "logging" and "nologging".  We do this because a bool
+// flag FLAG can be set from the command line to true with a "-FLAG"
+// argument, and to false with a "-noFLAG" argument, and so this can
+// potentially avert confusion.
+//
+// We also put flags into their own namespace.  It is purposefully
+// named in an opaque way that people should have trouble typing
+// directly.  The idea is that DEFINE puts the flag in the weird
+// namespace, and DECLARE imports the flag from there into the current
+// namespace.  The net result is to force people to use DECLARE to get
+// access to a flag, rather than saying "extern GFLAGS_DLL_DECL bool FLAGS_whatever;"
+// or some such instead.  We want this so we can put extra
+// functionality (like sanity-checking) in DECLARE if we want, and
+// make sure it is picked up everywhere.

+// Implement helpful bash-style command line flag completions
+//
+// ** Functional API:
+// HandleCommandLineCompletions() should be called early during
+// program startup, but after command line flag code has been
+// initialized, such as the beginning of HandleCommandLineHelpFlags().
+// It checks the value of the flag --tab_completion_word.  If this
+// flag is empty, nothing happens here.  If it contains a string,
+// however, then HandleCommandLineCompletions() will hijack the
+// process, attempting to identify the intention behind this
+// completion.  Regardless of the outcome of this deduction, the
+// process will be terminated, similar to --helpshort flag
+// handling.
+//
+// ** Overview of Bash completions:
+// Bash can be told to programatically determine completions for the
+// current 'cursor word'.  It does this by (in this case) invoking a
+// command with some additional arguments identifying the command
+// being executed, the word being completed, and the previous word
+// (if any).  Bash then expects a sequence of output lines to be
+// printed to stdout.  If these lines all contain a common prefix
+// longer than the cursor word, bash will replace the cursor word
+// with that common prefix, and display nothing.  If there isn't such
+// a common prefix, bash will display the lines in pages using 'more'.
+//
+// ** Strategy taken for command line completions:
+// If we can deduce either the exact flag intended, or a common flag
+// prefix, we'll output exactly that.  Otherwise, if information
+// must be displayed to the user, we'll take the opportunity to add
+// some helpful information beyond just the flag name (specifically,
+// we'll include the default flag value and as much of the flag's
+// description as can fit on a single terminal line width, as specified
+// by the flag --tab_completion_columns).  Furthermore, we'll try to
+// make bash order the output such that the most useful or relevent
+// flags are the most likely to be shown at the top.
+//
+// ** Additional features:
+// To assist in finding that one really useful flag, substring matching
+// was implemented.  Before pressing a <TAB> to get completion for the
+// current word, you can append one or more '?' to the flag to do
+// substring matching.  Here's the semantics:
+//   --foo<TAB>     Show me all flags with names prefixed by 'foo'
+//   --foo?<TAB>    Show me all flags with 'foo' somewhere in the name
+//   --foo??<TAB>   Same as prior case, but also search in module
+//                  definition path for 'foo'
+//   --foo???<TAB>  Same as prior case, but also search in flag
+//                  descriptions for 'foo'
+// Finally, we'll trim the output to a relatively small number of
+// flags to keep bash quiet about the verbosity of output.  If one
+// really wanted to see all possible matches, appending a '+' to the
+// search word will force the exhaustive list of matches to be printed.
+//
+// ** How to have bash accept completions from a binary:
+// Bash requires that it be informed about each command that programmatic
+// completion should be enabled for.  Example addition to a .bashrc
+// file would be (your path to gflags_completions.sh file may differ):
+
+/*
+$ complete -o bashdefault -o default -o nospace -C                            \
+ '/home/build/eng/bash/bash_completions.sh --tab_completion_columns $COLUMNS' \
+  time  env  binary_name  another_binary  [...]
+*/
+
+// This would allow the following to work:
+//   $ /path/to/binary_name --vmodule<TAB>
+// Or:
+//   $ ./bin/path/another_binary --gfs_u<TAB>
+// (etc)
+//
+// Sadly, it appears that bash gives no easy way to force this behavior for
+// all commands.  That's where the "time" in the above example comes in.
+// If you haven't specifically added a command to the list of completion
+// supported commands, you can still get completions by prefixing the
+// entire command with "env".
+//   $ env /some/brand/new/binary --vmod<TAB>
+// Assuming that "binary" is a newly compiled binary, this should still
+// produce the expected completion output.

+// thread-hostile: it is not safe for multiple threads to call this
+//   routine (or methods of this class) concurrently.  In gflags,
+//   most thread-hostile routines are intended to be called early in,
+//   or even before, main() -- that is, before threads are spawned.
+// thread-compatible: it is safe for multiple threads to read from
+//   this variable (when applied to variables), or to call const
+//   methods of this class (when applied to classes), as long as no
+//   other thread is writing to the variable or calling non-const
+//   methods of this class.

+// Now come the command line flag declaration/definition macros that
+// will actually be used.  They're kind of hairy.  A major reason
+// for this is initialization: we want people to be able to access
+// variables in global constructors and have that not crash, even if
+// their global constructor runs before the global constructor here.
+// (Obviously, we can't guarantee the flags will have the correct
+// default value in that case, but at least accessing them is safe.)
+// The only way to do that is have flags point to a static buffer.
+// So we make one, using a union to ensure proper alignment, and
+// then use placement-new to actually set up the flag with the
+// correct default value.  In the same vein, we have to worry about
+// flag access in global destructors, so FlagRegisterer has to be
+// careful never to destroy the flag-values it constructs.
+//
+// Note that when we define a flag variable FLAGS_<name>, we also
+// preemptively define a junk variable, FLAGS_no<name>.  This is to
+// cause a link-time error if someone tries to define 2 flags with
+// names like "logging" and "nologging".  We do this because a bool
+// flag FLAG can be set from the command line to true with a "-FLAG"
+// argument, and to false with a "-noFLAG" argument, and so this can
+// potentially avert confusion.
+//
+// We also put flags into their own namespace.  It is purposefully
+// named in an opaque way that people should have trouble typing
+// directly.  The idea is that DEFINE puts the flag in the weird
+// namespace, and DECLARE imports the flag from there into the current
+// namespace.  The net result is to force people to use DECLARE to get
+// access to a flag, rather than saying "extern GFLAGS_DLL_DECL bool FLAGS_whatever;"
+// or some such instead.  We want this so we can put extra
+// functionality (like sanity-checking) in DECLARE if we want, and
+// make sure it is picked up everywhere.

+// Implement helpful bash-style command line flag completions
+//
+// ** Functional API:
+// HandleCommandLineCompletions() should be called early during
+// program startup, but after command line flag code has been
+// initialized, such as the beginning of HandleCommandLineHelpFlags().
+// It checks the value of the flag --tab_completion_word.  If this
+// flag is empty, nothing happens here.  If it contains a string,
+// however, then HandleCommandLineCompletions() will hijack the
+// process, attempting to identify the intention behind this
+// completion.  Regardless of the outcome of this deduction, the
+// process will be terminated, similar to --helpshort flag
+// handling.
+//
+// ** Overview of Bash completions:
+// Bash can be told to programatically determine completions for the
+// current 'cursor word'.  It does this by (in this case) invoking a
+// command with some additional arguments identifying the command
+// being executed, the word being completed, and the previous word
+// (if any).  Bash then expects a sequence of output lines to be
+// printed to stdout.  If these lines all contain a common prefix
+// longer than the cursor word, bash will replace the cursor word
+// with that common prefix, and display nothing.  If there isn't such
+// a common prefix, bash will display the lines in pages using 'more'.
+//
+// ** Strategy taken for command line completions:
+// If we can deduce either the exact flag intended, or a common flag
+// prefix, we'll output exactly that.  Otherwise, if information
+// must be displayed to the user, we'll take the opportunity to add
+// some helpful information beyond just the flag name (specifically,
+// we'll include the default flag value and as much of the flag's
+// description as can fit on a single terminal line width, as specified
+// by the flag --tab_completion_columns).  Furthermore, we'll try to
+// make bash order the output such that the most useful or relevent
+// flags are the most likely to be shown at the top.
+//
+// ** Additional features:
+// To assist in finding that one really useful flag, substring matching
+// was implemented.  Before pressing a <TAB> to get completion for the
+// current word, you can append one or more '?' to the flag to do
+// substring matching.  Here's the semantics:
+//   --foo<TAB>     Show me all flags with names prefixed by 'foo'
+//   --foo?<TAB>    Show me all flags with 'foo' somewhere in the name
+//   --foo??<TAB>   Same as prior case, but also search in module
+//                  definition path for 'foo'
+//   --foo???<TAB>  Same as prior case, but also search in flag
+//                  descriptions for 'foo'
+// Finally, we'll trim the output to a relatively small number of
+// flags to keep bash quiet about the verbosity of output.  If one
+// really wanted to see all possible matches, appending a '+' to the
+// search word will force the exhaustive list of matches to be printed.
+//
+// ** How to have bash accept completions from a binary:
+// Bash requires that it be informed about each command that programmatic
+// completion should be enabled for.  Example addition to a .bashrc
+// file would be (your path to gflags_completions.sh file may differ):
+
+/*
+$ complete -o bashdefault -o default -o nospace -C                            \
+ '/home/build/eng/bash/bash_completions.sh --tab_completion_columns $COLUMNS' \
+  time  env  binary_name  another_binary  [...]
+*/
+
+// This would allow the following to work:
+//   $ /path/to/binary_name --vmodule<TAB>
+// Or:
+//   $ ./bin/path/another_binary --gfs_u<TAB>
+// (etc)
+//
+// Sadly, it appears that bash gives no easy way to force this behavior for
+// all commands.  That's where the "time" in the above example comes in.
+// If you haven't specifically added a command to the list of completion
+// supported commands, you can still get completions by prefixing the
+// entire command with "env".
+//   $ env /some/brand/new/binary --vmod<TAB>
+// Assuming that "binary" is a newly compiled binary, this should still
+// produce the expected completion output.
