The format of the programmer definition is as follows:
programmer
parent <id> # optional parent
id = <id1> [, <id2> ... ] ; # <idN> are quoted strings
desc = <description> ; # quoted string
type = <type>; # programmer type, quoted string
# supported types can be listed by "-c ?type"
prog_modes = PM_<i/f> { | PM_<i/f> } # interfaces, e.g., PM_SPM|PM_PDI
connection_type = parallel | serial | usb | spi
baudrate = <num> ; # baudrate for avr910-programmer
vcc = <pin1> [, <pin2> ... ] ; # pin number(s)
buff = <pin1> [, <pin2> ... ] ; # pin number(s)
reset = <pin> ; # pin number
sck = <pin> ; # pin number
sdo = <pin> ; # pin number
sdi = <pin> ; # pin number
errled = <pin> ; # pin number
rdyled = <pin> ; # pin number
pgmled = <pin> ; # pin number
vfyled = <pin> ; # pin number
usbvid = <hexnum> ; # USB VID (Vendor ID)
usbpid = <hexnum> [, <hexnum> ...] ; # USB PID (Product ID)
usbdev = <interface> ; # USB interface or other device info
usbvendor = <vendorname> ; # USB Vendor Name
usbproduct = <productname> ; # USB Product Name
usbsn = <serialno> ; # USB Serial Number
hvupdi_support = <num> [, <num>, ... ] ; # UPDI HV Variants Support

If a parent is specified, all settings of it (except its ids) are used for the new programmer. These values can be changed by new setting them for the new programmer.
Known programming modes are
PM_SPM: Bootloaders, self-programming with SPM opcodes or NVM Controllers
PM_TPI: Tiny Programming Interface (t4, t5, t9, t10, t20, t40, t102, t104)
PM_ISP: SPI programming for In-System Programming (almost all classic parts)
PM_PDI: Program and Debug Interface (xmega parts)
PM_UPDI: Unified Program and Debug Interface
PM_HVSP: High Voltage Serial Programming (some classic parts)
PM_HVPP: High Voltage Parallel Programming (most non-HVSP classic parts)
PM_debugWIRE: Simpler alternative to JTAG (a subset of HVPP/HVSP parts)
PM_JTAG: Joint Test Action Group standard (some classic parts)
PM_JTAGmkI: Subset of PM_JTAG, older parts, Atmel ICE mkI
PM_XMEGAJTAG: JTAG, some XMEGA parts
PM_AVR32JTAG: JTAG for 32-bit AVRs
PM_aWire: AVR32 parts
To invert a bit in the pin definitions, use = ~ <num>. To invert a pin list
(all pins get inverted) use ~ ( <num1> [, <num2> ... ] ).
Not all programmer types can handle a list of USB PIDs.
The following programmer types are currently implemented:
