+COMBINE_LANG_MODEL(1)
+=====================
+:doctype: manpage
+
+NAME
+----
+combine_lang_model - generate starter traineddata
+
+SYNOPSIS
+--------
+*combine_lang_model*  --input_unicharset 'filename' --script_dir 'dirname' --output_dir 'rootdir' --lang 'lang' [--lang_is_rtl] [pass_through_recoder] [--words file --puncs file --numbers file]
+
+DESCRIPTION
+-----------
+combine_lang_model(1) generates a starter traineddata file that can be used to train an LSTM-based neural network model. It takes as input a unicharset and an optional set of wordlists. It eliminates the need to run set_unicharset_properties(1), wordlist2dawg(1), some non-existent binary to generate the recoder (unicode compressor), and finally combine_tessdata(1).
+
+OPTIONS
+-------
+'--lang lang'::
+	The language to use.
+	Tesseract uses 3-character ISO 639-2 language codes. (See LANGUAGES)
+
+'--script_dir  PATH'::
+  Directory name for input script unicharsets. It should point to the location of langdata (github repo) directory.  (type:string default:)
+
+'--input_unicharset  FILE'::
+  Unicharset to complete and use in encoding. It can be a hand-created file with incomplete fields. Its basic and script properties will be set before it is used.  (type:string default:)
+
+'--lang_is_rtl  BOOL'::
+  True if language being processed is written right-to-left (eg Arabic/Hebrew). (type:bool default:false)
+
+'--pass_through_recoder BOOL'::
+  If true, the recoder is a simple pass-through of the unicharset. Otherwise, potentially a compression of it by encoding Hangul in Jamos, decomposing multi-unicode symbols into sequences of unicodes, and encoding Han using the data in the radical_table_data, which must be the content of the file: langdata/radical-stroke.txt. (type:bool default:false)
+
+'--version_str  STRING'::
+  An arbitrary version label to add to traineddata file  (type:string default:)
+
+'--words  FILE'::
+  (Optional) File listing words to use for the system dictionary  (type:string default:)
+
+'--numbers  FILE'::
+  (Optional) File listing number patterns  (type:string default:)
+
+'--puncs  FILE'::
+  (Optional) File listing punctuation patterns. The words/puncs/numbers lists may be all empty. If any are non-empty then puncs must be non-empty.  (type:string default:)
+
+'--output_dir   PATH'::
+  Root directory for output files. Output files will be written to <output_dir>/<lang>/<lang>.*  (type:string default:)
