NAME

vnroff - Vietnamese pre-processor for groff

SYNTAX

vnroff filename | groff [groff-options]

DESCRIPTION

This program processes a text file with special Vietnamese character sequences (VIQR syntax) giving an output suitable for groff(1) processing. The output should work for all point sizes supported by groff(1)

The default diacritical marks are defined as:
Dau_Sac ´ Dau_Huyen ` Dau_Hoi ? Dau_Nga ~ Dau_Nang . Dau_Mu ^ Dau_Trang ( Dau_Rau + Escape_Symbol \

SPELLING RULES

Only one diacritical mark:
vowel followed by symbol

Two diacritical marks:
vowel followed by Dau_Mu, Dau_Trang, Dau_Rau then other symbols.

DD and dd: self-explanatory, the resulting case is the same as the first character of the sequence.

The Escape_Symbol is provided to avoid the confusion between the diacritical marks and end-of-sentence symbols.
i.e: the question Anh ddi dda^u?
should be typed Anh ddi dda^u\?
