It's been a long time since I touched roff markup but this looks reasonable to me.

 .Nm
 is the command line interface for the LLDB debugger library.
 .Nm
 can debug C, C++, Objective-C, and Objective-C++ programs.
 .Pp
 The following options are available:
 .Bl -tag -width indent
 .It Fl h, -help
 Prints out the usage information for the
 .Nm
-debugger.  The \fB\-\-help\fR text may be more up-to-date and
+debugger.  The
+.Fl -help
+text may be more up-to-date and
 authoritative than the command line options described in this man
 page.
 .It Fl v, -version
 Prints out the version number of the
 .Nm
 debugger.
 .It Fl a, -arch Ar arch
 Specifies which architecture
 .Nm
 will use when launching the specified program (assuming the provided
 executable is built for multiple architectures.)
 .It Fl f, -file Ar filename
 Specifies the executable file that
 .Nm
 will be launching / attaching to.
 .It Fl n, -attach-name Ar process-name
 Specifies the name of a currently-running process to attach to.
-(or the name of a process to wait for if \fB\-w\fR is used.)
+(or the name of a process to wait for if
+.Fl w
+is used.)
 .It Fl w, -wait-for

+When used in concert with
+.Fl n Ar process-name ,
+indicates that
 .Nm
 should wait for a new process of that name to be started -- and attach
 to it as early in the process-launch as possible.
 .It Fl p, -attach-pid Ar pid
 Specifies a currently running process that
 .Nm
 should attach to.
 .It Fl l, -script-language Ar language
 Tells the debugger to use the specified scripting language for
 user-defined scripts, rather than the default.  Valid scripting
 languages that can be specified include Python, Perl, Ruby and Tcl.
 Currently only the Python extensions have been implemented.
 .It Fl d, -debug
 Tells the debugger to print out extra information for debugging itself.
 .It Fl s, -source Ar filename
 Tells
 .Nm
-to read in and execute the file "\fBfilename\fR", which
-should contain
+to read in and execute the file
+.Qq Ar filename ,
+which should contain
 .Nm
 commands.
 .It Fl e, -editor
 Instructs
 .Nm
 to open source files using the host's "external editor" mechanism.
 .It Fl x, -no-lldbinit
 Do not automatically parse any '.lldbinit' files.
 .Pp
 (If you don't provide -f then the first argument will be the file to be debugged
 so 'lldb -- <filename> [<ARG1> [<ARG2>]]' also works.
 Remember to end the options with "--" if any of your arguments have a "-" in them.)

 .Sh USING LLDB
 In
 .Nm
-there is a \fBhelp\fR command which can be used to find descriptions and examples of
-all
-.Nm
-commands.  To get help on "\fBbreakpoint set\fR" you would type "\fBhelp breakpoint set\fR".
-.Pp
-There is also an \fBapropos\fR command which will search the help text of all commands
-for a given term -- this is useful for locating a command by topic.  For instance, "\fBapropos breakpoint\fR"
-will list any command that has the word \fBbreakpoint\fR in its help text.
+there is a
+.Cm help
+command which can be used to find descriptions and examples of all

 .Sh FILES
 .Nm
 will read settings/aliases/commands from three files at startup, if they exist.
 .Pp
 First, it will read a \fB~/.lldbinit-\fIdebugger\fR command file.  If you are using the
 .Nm
 command line interface, this is \fB~/.lldbinit-lldb\fR.  If you are using
 .Nm
