+@cindex php-fpm
+PHP-FPM (FastCGI Process Manager) is an alternative PHP FastCGI implementation
+with some additional features useful for sites of any size.
+
+These features include:
+@itemize @bullet
+@item Adaptive process spawning
+@item Basic statistics (similar to Apache's mod_status)
+@item Advanced process management with graceful stop/start
+@item Ability to start workers with different uid/gid/chroot/environment
+and different php.ini (replaces safe_mode)
+@item Stdout & stderr logging
+@item Emergency restart in case of accidental opcode cache destruction
+@item Accelerated upload support
+@item Support for a "slowlog"
+@item Enhancements to FastCGI, such as fastcgi_finish_request() -
+a special function to finish request & flush all data while continuing to do
+something time-consuming (video converting, stats processing, etc.)
+@end itemize
+... and much more.
+
+@defvr {Scheme Variable} php-fpm-service-type
+A Service type for @code{php-fpm}.
+@end defvr
+
+@deftp {Data Type} php-fpm-configuration
+Data Type for php-fpm service configuration.
+@table @asis
+@item @code{php} (default: @code{php})
+The php package to use.
+@item @code{socket} (default: @code{(string-append "/var/run/php" (version-major (package-version php)) "-fpm.sock")})
+The address on which to accept FastCGI requests. Valid syntaxes are:
+@table @asis
+@item @code{"ip.add.re.ss:port"}
+Listen on a TCP socket to a specific address on a specific port.
+@item @code{"port"}
+Listen on a TCP socket to all addresses on a specific port.
+@item @code{"/path/to/unix/socket"}
+Listen on a unix socket.
+@end table
+
+@item @code{user} (default: @code{php-fpm})
+User who will own the php worker processes.
+@item @code{group} (default: @code{php-fpm})
+Group of the worker processes.
+@item @code{socket-user} (default: @code{php-fpm})
+User who can speak to the php-fpm socket.
+@item @code{socket-group} (default: @code{php-fpm})
+Group that can speak to the php-fpm socket.
+@item @code{pid-file} (default: @code{(string-append "/var/run/php" (version-major (package-version php)) "-fpm.pid")})
+The process id of the php-fpm process is written to this file
+once the service has started.
+@item @code{log-file} (default: @code{(string-append "/var/log/php" (version-major (package-version php)) "-fpm.log")})
+Log for the php-fpm master process.
+@item @code{process-manager} (default: @code{(php-fpm-dynamic-process-manager-configuration)})
+Detailed settings for the php-fpm process manager.
+Must be either:
+@table @asis
+@item @code{<php-fpm-dynamic-process-manager-configuration>}
+@item @code{<php-fpm-static-process-manager-configuration>}
+@item @code{<php-fpm-on-demand-process-manager-configuration>}
+@end table
+@item @code{display-errors} (default @code{#f})
+Determines wether php errors and warning should be sent to clients
+and displayed in their browsers.
+This is useful for local php development, but a security risk for public sites,
+as error messages can reveal passwords and personal data.
+@item @code{workers-logfile} (default @code{(string-append "/var/log/php" (version-major (package-version php)) "-fpm.www.log")})
+This file will log the @code{stderr} outputs of php worker processes.
+Can be set to @code{#f} to disable logging.
+@item @code{file} (default @code{#f})
+An optional override of the whole configuration.
+You can use the @code{mixed-text-file} function or an absolute filepath for it.
