As per Wikipedia, Linguistics is the scientific study of language, specifically language form, language meaning, and language in context. The earliest activities in the description of language have been attributed to the 4th century BCE Indian grammarian Pāṇini, who was an early student of inguistics and wrote a formal description of the Sanskrit language in his Aṣṭādhyāyī.
As everyone knows Language is the most important tool to communicate and bring the world together. Along with syntactic trees and specialized fonts for a variety of languages and phonetic symbols, the scholarly output for linguistic journals such as Gloss requires an accurate rendering of interlinear glosses.
To make open access model and publishing of linguistics would be first motivation for all. These glosses often result in blocky forms of text, including special characters and diacritics, which must be aligned perfectly with the line above it.If you want to get more information, catch up with the articles here http://goo.gl/JnbuQb.
