firstindexletter – Enlarged initials for the first entries of index letter groups

This LaTeX package helps to visually emphasize the first item of each index letter group by enlarging its initial letter.

The package is intended primarily for indexes generated with xindy/texindy. It works at LaTeX macro level: instead of modifying the generated .ind file, it hooks into the index environment and formats the first entry of each effective letter group.

The package provides configurable initial size, font family and color, and includes simple optical kerning adjustments for selected initial-letter pairs. It also supports Hungarian multi-character initials such as Cs, Gy, Ly, Ny, Sz, Ty and Zs, with configurable handling of Dz and Dzs.

The distribution includes the package file, documentation, examples, and a Hungarian manual.
