+.SH "SYNOPSIS"

+.SH "OPTIONS"
+.sp
+picchick accepts some common configuration options that dictate how to go about
+performing the action. Other options provide information about picchick itself.
+The programmer flag is required for all actions that involve a programmer.
+The device flag is required for all actions that involve a device.
+.sp
+\fB\-c <programmer>\fP
+.RS 4
+The name of the programmer to use. Different programmers
+require different options, see the programmer\(cqs options with
+\f(CRpicchick \-c <programmer> \-h\fP.
+.RE
+.sp
+\fB\-d, \-\-device <mcu>\fP
+.RS 4
+The device being programmed. The \fImcu\fP argument is either
+a chip part number, or a path to a custom device file.
+.RE
+.sp
+\fB\-\-version\fP
+.RS 4
+Print the version number and exit.
+.RE
+.sp
+\fB\-h, \-\-help\fP
+.RS 4
+Print usage information and a short help message. Can be
+combined with \f(CR\-c\fP to get help about a specific programmer.
+.RE
+.SH "ACTIONS"
+.sp
+At least one action is required, else picchick would have nothing to do! Some
+actions cannot be used together, i.e. you cannot flash and write in the same
+command. Other actions can be chained, for instance you can erase a device,
+flash a hexfile, then verify the memory in one command.
+.sp
+\fB\-r, \-\-read <addr> [len]\fP
+.RS 4
+Read \fIlength\fP words starting from \fIaddr\fP. Length
+defaults to 2 if omitted.
+.RE
+.sp
+\fB\-w, \-\-write <addr> <word>\fP
+.RS 4
+Write \fIword\fP to \fIaddress\fP.

+Flash \fIhexfile\fP to device.
+.RE
+.sp
+\fB\-e, \-\-erase [addr]\fP
+.RS 4
+Erase \fIaddr\fP. Address can be a hex number, \*(Aqall\*(Aq or \*(Aqflash\*(Aq.
+.RE
+.sp
+\fB\-v, \-\-verify\fP
+.RS 4
+Verify written data. This can be used with either the write or
+flash actions, or by itself to verify against a hexfile.
+.RE

+Pretty print \fIhexfile\fP, mapped to \fIdevice\fP if the \f(CR\-d\fP flag is given.
