+Dependencies: liburcu (Userspace RCU) is required at runtime.
+
+`pkg-config', GNU make, and standard Perl build tools are also required.
+
+             FreeBSD:        pkg install pkg-config liburcu
+Debian-based systems:        apt-get install pkg-config liburcu-dev
+
+
+Newer versions of xxhash can unlock a small bit of performance:
+
+        pkg install xxhash
+        apt-get install libxxhash-dev
+
+
+If using mwrap-rproxy, Plack is also required:
+
+        pkg install p5-Plack p5-Plack-Middleware-Deflater
+        apt-get install libplack-perl libplack-middleware-deflater-perl
+
+symlink-install
+---------------
+
+For users who lack permissions and/or wish to minimize their
+installation footprint, the "symlink-install" target is available.
+The following commands installs symlinks to $HOME/bin
+pointing to the source tree:
+
+        perl Makefile.PL
+        make symlink-install prefix=$HOME
+
+standard MakeMaker installation (Perl)
+--------------------------------------
+
+To use MakeMaker, you need to ensure ExtUtils::MakeMaker is available.
+This is typically installed with Perl, but RPM-based systems will likely
+need to install the `perl-ExtUtils-MakeMaker' package.
+
+Once the dependencies are installed, you should be able to build and
+install the system (into /usr/local) with:
+
+        perl Makefile.PL
+        make
+        make check
+        make install # root permissions may be needed

-= mwrap - LD_PRELOAD malloc wrapper + line stats for Ruby

-mwrap is designed to answer the question:
+Devel::Mwrap is designed to answer the question:
 
-   Which lines of Ruby are hitting malloc the most?
+   Which lines of Perl are hitting malloc the most?
 
-mwrap wraps all malloc-family calls to trace the Ruby source
-location of such calls and bytes allocated at each callsite.
-As of mwrap 2.0.0, it can also function as a leak detector
-and show live allocations at every call site.  Depending on
-your application and workload, the overhead is roughly a 50-100%
-increase memory and runtime with default settings.
+Devel::Mwrap wraps all malloc-family calls to trace the Perl source
+location of such calls and bytes allocated at each callsite.  It
+can also function as a leak detector and show live allocations
+at every call site.  Depending on your application and workload,
+the overhead is roughly a 50%-100% increase memory and runtime.
 
-It works best for allocations under GVL, but tries to track
-numeric caller addresses for allocations made without GVL so you
-can get an idea of how much memory usage certain extensions and
-native libraries use.
+It is thread-safe and requires the concurrent lock-free hash table

+It relies on dynamic linking to a malloc(3) implementation.  If

-It does not require recompiling or rebuilding Ruby, but only

+=head1 COMPATIBILITY
+
+This version of F<ppport.h> is designed to support operation with Perl
+installations back to 5.003, and has been tested up to 5.20.
+
+=head1 OPTIONS
+
+=head2 --help
+
+Display a brief usage summary.
+
+=head2 --version
+
+Display the version of F<ppport.h>.
+
+=head2 --patch=I<file>
+
+If this option is given, a single patch file will be created if
+any changes are suggested. This requires a working diff program
+to be installed on your system.
+
+=head2 --copy=I<suffix>
+
+If this option is given, a copy of each file will be saved with
+the given suffix that contains the suggested changes. This does
+not require any external programs. Note that this does not
+automagically add a dot between the original filename and the
+suffix. If you want the dot, you have to include it in the option
+argument.
+
+If neither C<--patch> or C<--copy> are given, the default is to
+simply print the diffs for each file. This requires either
+C<Text::Diff> or a C<diff> program to be installed.
+
+=head2 --diff=I<program>
+
+Manually set the diff program and options to use. The default
+is to use C<Text::Diff>, when installed, and output unified
+context diffs.
+
+=head2 --compat-version=I<version>
+
+Tell F<ppport.h> to check for compatibility with the given
+Perl version. The default is to check for compatibility with Perl
+version 5.003. You can use this option to reduce the output
+of F<ppport.h> if you intend to be backward compatible only
+down to a certain Perl version.
+
+=head2 --cplusplus
+
+Usually, F<ppport.h> will detect C++ style comments and
+replace them with C style comments for portability reasons.
+Using this option instructs F<ppport.h> to leave C++
+comments untouched.
+
+=head2 --quiet
+
+Be quiet. Don't print anything except fatal errors.
+
+=head2 --nodiag
+
+Don't output any diagnostic messages. Only portability
+alerts will be printed.
+
+=head2 --nohints
+
+Don't output any hints. Hints often contain useful portability
+notes. Warnings will still be displayed.
+
+=head2 --nochanges
+
+Don't suggest any changes. Only give diagnostic output and hints
+unless these are also deactivated.
+
+=head2 --nofilter
+
+Don't filter the list of input files. By default, files not looking
+like source code (i.e. not *.xs, *.c, *.cc, *.cpp or *.h) are skipped.
+
+=head2 --strip
+
+Strip all script and documentation functionality from F<ppport.h>.
+This reduces the size of F<ppport.h> dramatically and may be useful
+if you want to include F<ppport.h> in smaller modules without
+increasing their distribution size too much.
+
+The stripped F<ppport.h> will have a C<--unstrip> option that allows
+you to undo the stripping, but only if an appropriate C<Devel::PPPort>
+module is installed.
+
+=head2 --list-provided
+
+Lists the API elements for which compatibility is provided by
+F<ppport.h>. Also lists if it must be explicitly requested,
+if it has dependencies, and if there are hints or warnings for it.
+
+=head2 --list-unsupported
+
+Lists the API elements that are known not to be supported by
+F<ppport.h> and below which version of Perl they probably
+won't be available or work.
+
+=head2 --api-info=I<name>
+
+Show portability information for API elements matching I<name>.
+If I<name> is surrounded by slashes, it is interpreted as a regular
+expression.
+
+=head1 DESCRIPTION
+
+In order for a Perl extension (XS) module to be as portable as possible
+across differing versions of Perl itself, certain steps need to be taken.
+
+=over 4
+
+=item *
+
+Including this header is the first major one. This alone will give you
+access to a large part of the Perl API that hasn't been available in
+earlier Perl releases. Use
+
+    perl ppport.h --list-provided
+
+to see which API elements are provided by ppport.h.
+
+=item *
+
+You should avoid using deprecated parts of the API. For example, using
+global Perl variables without the C<PL_> prefix is deprecated. Also,
+some API functions used to have a C<perl_> prefix. Using this form is
+also deprecated. You can safely use the supported API, as F<ppport.h>
+will provide wrappers for older Perl versions.
+
+=item *
+
+If you use one of a few functions or variables that were not present in
+earlier versions of Perl, and that can't be provided using a macro, you
+have to explicitly request support for these functions by adding one or
+more C<#define>s in your source code before the inclusion of F<ppport.h>.
+
+These functions or variables will be marked C<explicit> in the list shown
+by C<--list-provided>.
+
+Depending on whether you module has a single or multiple files that
+use such functions or variables, you want either C<static> or global
+variants.
+
+For a C<static> function or variable (used only in a single source
+file), use:
+
+    #define NEED_function
+    #define NEED_variable
+
+For a global function or variable (used in multiple source files),
+use:
+
+    #define NEED_function_GLOBAL
+    #define NEED_variable_GLOBAL
+
+Note that you mustn't have more than one global request for the
+same function or variable in your project.

+
+To avoid namespace conflicts, you can change the namespace of the
+explicitly exported functions / variables using the C<DPPP_NAMESPACE>
+macro. Just C<#define> the macro before including C<ppport.h>:
+
+    #define DPPP_NAMESPACE MyOwnNamespace_
+    #include "ppport.h"
+
+The default namespace is C<DPPP_>.
+
+=back
+
+The good thing is that most of the above can be checked by running
+F<ppport.h> on your source code. See the next section for
+details.
+
+=head1 EXAMPLES
+
+To verify whether F<ppport.h> is needed for your module, whether you
+should make any changes to your code, and whether any special defines
+should be used, F<ppport.h> can be run as a Perl script to check your
+source code. Simply say:
+
+    perl ppport.h
+
+The result will usually be a list of patches suggesting changes
+that should at least be acceptable, if not necessarily the most
+efficient solution, or a fix for all possible problems.
+
+If you know that your XS module uses features only available in
+newer Perl releases, if you're aware that it uses C++ comments,
+and if you want all suggestions as a single patch file, you could
+use something like this:
+
+    perl ppport.h --compat-version=5.6.0 --cplusplus --patch=test.diff
+
+If you only want your code to be scanned without any suggestions
+for changes, use:
+
+    perl ppport.h --nochanges
+
+You can specify a different C<diff> program or options, using
+the C<--diff> option:
+
+    perl ppport.h --diff='diff -C 10'
+
+This would output context diffs with 10 lines of context.
+
+If you want to create patched copies of your files instead, use:
+
+    perl ppport.h --copy=.new
+
+To display portability information for the C<newSVpvn> function,

+=head1 NAME
+
+mwrap-rproxy - reverse proxy for embedded per-process mwrap httpd
+
+=head1 SYNOPSIS
+
+  # start the long-running COMMAND you wish to trace:
+  MWRAP=socket_dir:$DIR mwrap-perl COMMAND
+
+  # in a different terminal, point mwrap-proxy to the mwrap-perl socket_dir
+  mwrap-rproxy --socket-dir=$DIR -l 127.0.0.1:8080
+
+  # open http://127.0.0.1:8080/ in your favorite web browser:
+  w3m http://127.0.0.1:8080/
+
+=head1 DESCRIPTION
+
+B<mwrap-rproxy> is a PSGI reverse proxy to provide access
+via TCP to the native, Unix-socket-only httpd embedded inside
+mwrap core.  It provides a listing of process IDs of each process
+traced via mwrap.
+
+B<mwrap-rproxy> does not have a hard dependency on mwrap-perl itself,
+it exists to provide a convenient interface to programs being
+traced by mwrap-perl.
+
+=head1 OPTIONS
+
+=over 4
+
+=item --socket-dir=DIR
+
+If unset, it will attempt to parse C<socket_dir:> from the C<MWRAP>
+environment (see L<mwrap-perl(1p)>).
+
+=item --no-deflate
+
+L<Plack::Middleware::Deflater(3pm)> is loaded by default if available.
+Using C<--no-deflate> will save CPU cycles at the expense of bandwidth.
+
+=back
+
+Additionally, all options in L<plackup(1p)> are supported.  Notably,
+C<-l>/C<--listen> and C<--path=/prefix> may be useful.
+
+=head1 ENVIRONMENT
+
+mwrap-rproxy supports systemd (and compatible) socket activation via
+C<LISTEN_PID> and C<LISTEN_FDS> variables.  See L<systemd.socket(5)>
+and L<sd_listen_fds(3)>.
+
+C<PLACK_ENV> is also supported as described by L<plackup(1p)>
