Every platform is defined in an `.ini` file with an appropriate name.
#### `[compilation]` section
*`arch`– CPU architecture. It defines which instructions are available. Available values:
*`nmos`
*`strict` (= NMOS without illegal instructions)
*`ricoh` (= NMOS without decimal mode)
*`strictricoh`
*`cmos` (= 65C02)
*`modules`– comma-separated list of modules that will be automatically imported
* other compilation options (they can be overridden using commandline options):
*`emit_illegals`– whether the compiler should emit illegal instructions, default `false`
*`emit_cmos`– whether the compiler should emit CMOS instructions, default is `true` on `cmos` and `false` elsewhere
*`decimal_mode`– whether the compiler should emit decimal instructions, default is `false` on `ricoh` and `strictricoh` and `true` elsewhere
*`ro_arrays`– whether the compiler should warn upon array writes, default is `false`
*`prevent_jmp_indirect_bug`– whether the compiler should try to avoid the indirect JMP bug, default is `false` on `cmos` and `true` elsewhere
#### `[allocation]` section
*`main_org`– the address for the `main` function; all the other functions will be placed after it
*`zp_pointers`– either a list of comma separated zeropage addresses that can be used by the program as zeropage pointers, or `all` for all. Each value should be the address of the first of two free bytes in the zeropage.
*`himem_style`– not yet supported
*`himem_start`– the first address used for non-zeropage variables, or `after_code` if the variables should be allocated after the code
*`himem_end`– the last address available for non-zeropage variables
#### `[output]` section
*`style`– not yet supported
*`format`– output file format; a comma-separated list of tokens:
* literal byte values
*`startaddr`– little-endian 16-bit address of the first used byte of the compiled output
*`endaddr`– little-endian 16-bit address of the last used byte of the compiled output
*`allocated`– all used bytes
*`<addr>:<addr>` - inclusive range of bytes
*`extension`– target file extension, with or without the dot
