Introduction
Language files are usually found in the lang sub-folder of the project, but the place NML looks for the language files can be changed via command line parameter to any directory desired:
nmlc -l path/to/lang-dir path/to/nml-source-file.nml nmlc --lang-dir=path/to/lang-dir path/to/nml-source-file.nml
Language files MUST have the extension .lng
The language files themselves follow a certain structure:
##grflangid <number> <string-name> :<text> <string-name> :<text> ...
where the first line must give the language code for the language this file describes (see below). The following lines each describe a string. The translated string follows immediately the colon. An NML project has exactly one fallback language, by default this is english.lng. You can change this with the command line parameter --default-lang. Example for a valid language file:
##grflangid 0x01
STR_GRF_NAME :{TITLE} 0.1.0 - {VERSION}
STR_GRF_DESCRIPTION :{TITLE} contains pimped ground tiles.
STR_NAME_MYVEHICLE :General Robotics Anti-Grav UFO Mark X
String codes
Strings may contain a number of special string codes which control how the string is being printed or which values to insert into the string. Custom replacements can be stored in the plain text file custom_tags.txt (for example a newgrf version which is written by your build script). In the case above the custom_tags.txt could, for example read
VERSION :alpha-r88 TITLE :Example NewGRF
Additionally to custom-defined tags, NML comes with a number of default tags:

Defining cases
Similar to OpenTTD's language files, NML can also make use of cases, genders and plural forms. In order to utilize them, they have to be defined in the language file's header and have to match the definition as used in OpenTTD's language files:
##case pragma STR_NAME :Utas STR_NAME.pragma :utast
e.g. for Hungarian you'd have
##case t ba STR_CARGO_PLURAL_PASSENGERS :Utas STR_CARGO_PLURAL_PASSENGERS.t :utast
Defining genders
Genders just like cases are defined in the header of the language file and have to match the definition as found within OpenTTD's language files. The gender of a word or expression is declared within the string's text itself by a tag of the form {G=gendername}:
##gender pragma
STR_NAME :{G=gendername}String which requires gender 'gendername'
where the string with the defined gender then will trigger the correct usage in a string which includes it and which has to take provisions to show the proper gender:
STR_OTHER :Some text {G gender1 gender2 ...} {STRING}
for example in German
##gender m w n p
STR_CARGO_NAME_BAUXITE :{G=n}Bauxit
which then will be used with the correct gender by a string which includes it:
STR_NEWS_STATION_NO_LONGER_ACCEPTS_CARGO :{WHITE}{STATION} akzeptiert kein{G "en" "e" "" "e"} {STRING} mehr.

In case a language is not in this list, check the master language list (for GRFv7) in the NewGRF Specs. This master list is always leading. NFO language ID 7F has no meaning in NML (set --default-lang instead) and setting bit 16 will break your language file.
