.br
.B lrelease
.RI "[ " options " ] " ts-files " [ -qm " qm-file " ]"
.SH DESCRIPTION
This page documents the
.B Qt Linguist Release
tool for the Qt GUI toolkit.
.B Lrelease
reads a qmake/tmake project file (.pro file) and converts the
translation files (TS files) specified in it into Qt message files
(QM files) used by the application to translate.
.PP
The QM file format is a compact binary format that provides
extremely fast lookups for translations and that is used by Qt.
.SH OPTIONS
.TP
.I "-help"
Display the usage and exit.
.TP
.I "-compress"
Compress the QM files.
.TP
.I "-nounfinished"
Do not include unfinished translations.
.TP
.I "-removeidentical"
If the translated text is the same as
the source text, do not include the message.
.TP
.I "-silent"
Do not explain what is being done.
.TP
.I "-version"
Display the version of
.B lrelease
and exit.
.SH USAGE
Here is an example .pro file that can be given to
.B lrelease:
.PP
.in +4
.nf
HEADERS = funnydialog.h \\
wackywidget.h
SOURCES = funnydialog.cpp \\
main.cpp \\
wackywidget.cpp
FORMS = fancybox.ui
TRANSLATIONS = gnomovision_dk.ts \\
gnomovision_fi.ts \\
gnomovision_no.ts \\
gnomovision_se.ts
.fi
.in -4
.PP
When running
.B lrelease
on this project file, the Qt message files gnomovision_dk.qm,
gnomovision_fi.qm, gnomovision_no.qm and gnomovision_se.qm will be
generated from gnomovision_dk.ts, gnomovision_fi.ts,
gnomovision_no.ts and gnomovision_se.ts, respectively.
.PP
.B Lrelease
can also be invoked with a list of TS files to convert:
.PP
