.SH DESCRIPTION

This page documents the

.B Qt Linguist Update

tool for the Qt GUI toolkit.

.B Lupdate

reads a qmake/tmake project file (.pro file), finds the translatable

strings in the specified source, header and interface files, and

updates the translation files (TS files) specified in it. The

translation files are given to the translator who uses

.B Qt Linguist

to read the files and insert the translations.

.PP

The TS file format is a simple human-readable XML format that can be

used with version control systems if required.
