+.SH NAME
+Test2::Util \- Tools used by Test2 and friends.
+.SH DESCRIPTION
+.IX Header "DESCRIPTION"
+Collection of tools used by Test2 and friends.
+.SH EXPORTS
+.IX Header "EXPORTS"
+All exports are optional. You must specify subs to import.
+.ie n .IP "($success, $error) = try { ... }" 4
+.el .IP "($success, \f(CW$error\fR) = try { ... }" 4
+.IX Item "($success, $error) = try { ... }"
+Eval the codeblock, return success or failure, and the error message. This code
+protects $@ and $!, they will be restored by the end of the run. This code also
+temporarily blocks \f(CW$SIG\fR{DIE} handlers.
+.IP "protect { ... }" 4
+.IX Item "protect { ... }"
+Similar to try, except that it does not catch exceptions. The idea here is to
+protect $@ and $! from changes. $@ and $! will be restored to whatever they
+were before the run so long as it is successful. If the run fails $! will still
+be restored, but $@ will contain the exception being thrown.
+.IP CAN_FORK 4
+.IX Item "CAN_FORK"
+True if this system is capable of true or pseudo-fork.
+.IP CAN_REALLY_FORK 4
+.IX Item "CAN_REALLY_FORK"
+True if the system can really fork. This will be false for systems where fork
+is emulated.
+.IP CAN_THREAD 4
+.IX Item "CAN_THREAD"
+True if this system is capable of using threads.
+.IP USE_THREADS 4
+.IX Item "USE_THREADS"
+Returns true if threads are enabled, false if they are not.
+.IP get_tid 4
+.IX Item "get_tid"
+This will return the id of the current thread when threads are enabled,
+otherwise it returns 0.
+.ie n .IP "my $file = pkg_to_file($package)" 4
+.el .IP "my \f(CW$file\fR = pkg_to_file($package)" 4
+.IX Item "my $file = pkg_to_file($package)"
+Convert a package name to a filename.
+.ie n .IP "$string = \fBipc_separator()\fR" 4
+.el .IP "\f(CW$string\fR = \fBipc_separator()\fR" 4
+.IX Item "$string = ipc_separator()"
+Get the IPC separator. Currently this is always the string \f(CW\*(Aq~\*(Aq\fR.
+.ie n .IP "$string = \fBgen_uid()\fR" 4
+.el .IP "\f(CW$string\fR = \fBgen_uid()\fR" 4
+.IX Item "$string = gen_uid()"
+Generate a unique id (NOT A UUID). This will typically be the process id, the
+thread id, the time, and an incrementing integer all joined with the
+\&\f(CWipc_separator()\fR.
+.Sp
+These ID's are unique enough for most purposes. For identical ids to be
+generated you must have 2 processes with the same PID generate IDs at the same
+time with the same current state of the incrementing integer. This is a
+perfectly reasonable thing to expect to happen across multiple machines, but is
+quite unlikely to happen on one machine.
+.Sp
+This can fail to be unique if a process generates an id, calls exec, and does
+it again after the exec and it all happens in less than a second. It can also
+happen if the systems process id's cycle in less than a second allowing 2
+different programs that use this generator to run with the same PID in less
+than a second. Both these cases are sufficiently unlikely. If you need
+universally unique ids, or ids that are unique in these conditions, look at
+Data::UUID.
+.ie n .IP "($ok, $err) = do_rename($old_name, $new_name)" 4
+.el .IP "($ok, \f(CW$err\fR) = do_rename($old_name, \f(CW$new_name\fR)" 4
+.IX Item "($ok, $err) = do_rename($old_name, $new_name)"
+Rename a file, this wraps \f(CWrename()\fR in a way that makes it more reliable
+cross-platform when trying to rename files you recently altered.
+.ie n .IP "($ok, $err) = do_unlink($filename)" 4
+.el .IP "($ok, \f(CW$err\fR) = do_unlink($filename)" 4
+.IX Item "($ok, $err) = do_unlink($filename)"
+Unlink a file, this wraps \f(CWunlink()\fR in a way that makes it more reliable
+cross-platform when trying to unlink files you recently altered.
+.ie n .IP "($ok, $err) = try_sig_mask { ... }" 4
+.el .IP "($ok, \f(CW$err\fR) = try_sig_mask { ... }" 4
+.IX Item "($ok, $err) = try_sig_mask { ... }"
+Complete an action with several signals masked, they will be unmasked at the
+end allowing any signals that were intercepted to get handled.
+.Sp
+This is primarily used when you need to make several actions atomic (against
+some signals anyway).
+.Sp
+Signals that are intercepted:

+.IP SIGINT 4
+.IX Item "SIGINT"
+.PD 0
+.IP SIGALRM 4
+.IX Item "SIGALRM"
+.IP SIGHUP 4

+.SH "NOTES && CAVEATS"
+.IX Header "NOTES && CAVEATS"
+.IP 5.10.0 4
+.IX Item "5.10.0"
+Perl 5.10.0 has a bug when compiled with newer gcc versions. This bug causes a
+segfault whenever a new thread is launched. Test2 will attempt to detect
+this, and note that the system is not capable of forking when it is detected.
+.IP Devel::Cover 4
+.IX Item "Devel::Cover"
+Devel::Cover does not support threads. CAN_THREAD will return false if
+Devel::Cover is loaded before the check is first run.
