-== Name
-
-crashpad_handler - Crashpad’s exception handler server
-
-== Synopsis
-
-[verse]
-*crashpad_handler* ['OPTION…']
-
-== Description
-
-This program is Crashpad’s main exception-handling server. It is responsible for
-catching exceptions, writing crash reports, and uploading them to a crash report
-collection server. Uploads are disabled by default, and can only be enabled by a
-Crashpad client using the Crashpad client library, typically in response to a
-user requesting this behavior.
-
-This server is normally started by its initial client, and it performs a
-handshake with this client via a pipe established by the client that is
-inherited by the server, referenced by the *--handshake-fd* argument. During the
-handshake, the server furnishes the client with a send right that the client may
-use as an exception port. The server retains the corresponding receive right,
-which it monitors for exception messages. When the receive right loses all
-senders, the server exits after allowing any upload in progress to complete.
-
-It is not normally appropriate to invoke this program directly. Usually, it will
-be invoked by a Crashpad client using the Crashpad client library. Arbitrary
-programs may be run with a Crashpad handler by using
-man_link:run_with_crashpad[1] to establish the Crashpad client environment
-before running a program.
-
-== Options
-*--annotation*='KEY=VALUE'::
-Sets a process-level annotation mapping 'KEY' to 'VALUE' in each crash report
-that is written. This option may appear zero, one, or multiple times.
-+
-Most annotations should be provided by the Crashpad client as module-level
-annotations instead of process-level annotations. Module-level annotations are
-more flexible in that they can be modified and cleared during the client
-program’s lifetime. Module-level annotations can be set via the Crashpad client
-library. Process-level annotations are useful for annotations that the
-collection server requires be present, that have fixed values, and for cases
-where a program that does not use the Crashpad client library is being
-monitored.
-+
-Breakpad-type collection servers only require the +"prod"+ and +"ver"+
-annotations, which should be set to the product name or identifier and product
-version, respectively. It is unusual to specify other annotations as
-process-level annotations via this argument.
-
-*--database*='PATH'::
-Use 'PATH' as the path to the Crashpad crash report database. This option is
-required. Crash reports are written to this database, and if uploads are
-enabled, uploaded from this database to a crash report collection server. If the
-database does not exist, it will be created, provided that the parent directory
-of 'PATH' exists.
-
-*--handshake-fd*='FD'::
-Perform the handshake with the initial client on the file descriptor at 'FD'.
-This option is required.
-
-*--url*='URL'::
-If uploads are enabled, sends crash reports to the Breakpad-type crash report
-collection server at 'URL'. Uploads are disabled by default, and can only be
-enabled for a database by a Crashpad client using the Crashpad client library,
-typically in response to a user requesting this behavior. If this option is not
-specified, this program will behave as if uploads are disabled.
-
-*--help*::
-Display help and exit.
-
-*--version*::
-Output version information and exit.
-
-== Exit Status
-
-*0*::
-Success.
-
-*1*::
-Failure, with a message printed to the standard error stream.
