.SH "DESCRIPTION"
.IX Header "DESCRIPTION"
The \fBl2\-config\fR program is a little helper utility for easy configuring and
building applications based on the \fIl2\fR\|(3) library.  It can be used to query the
C compiler and linker flags which are required to correctly compile and link
the application against the \fIl2\fR\|(3) library.
.SH "OPTIONS"
.IX Header "OPTIONS"
\&\fBl2\-config\fR accepts the following options:
.Ip "\fB\*(--help\fR" 4
.IX Item "help"
Prints the short usage information.
.Ip "\fB\*(--version\fR" 4
.IX Item "version"
Prints the version number and date of the installed \fIl2\fR\|(3) library.
.Ip "\fB\*(--all\fR" 4
.IX Item "all"
Forces the output of all flags, that is, including extra flags which are not
\&\fBL2\fR specific.
.Ip "\fB\*(--prefix\fR" 4
.IX Item "prefix"
Prints the installation prefix of architecture independent files
.Ip "\fB\*(--exec-prefix\fR" 4
.IX Item "exec-prefix"
Prints the installation prefix of architecture dependent files.
.Ip "\fB\*(--bindir\fR" 4
.IX Item "bindir"
Prints the installation directory of binaries.
.Ip "\fB\*(--libdir\fR" 4
.IX Item "libdir"
Prints the installation directory of libraries.
.Ip "\fB\*(--includedir\fR" 4
.IX Item "includedir"
Prints the installation directory of include headers.
.Ip "\fB\*(--mandir\fR" 4
.IX Item "mandir"
Prints the installation directory of manual pages.
.Ip "\fB\*(--datadir\fR" 4
.IX Item "datadir"
Prints the installation directory of shared data.
.Ip "\fB\*(--acdir\fR" 4
.IX Item "acdir"
Prints the installation directory of \fBautoconf\fR data.
.Ip "\fB\*(--cflags\fR" 4
.IX Item "cflags"
Prints the C compiler flags which are needed to compile the \fIl2\fR\|(3)\-based
application. The output is usually added to the \f(CW\*(C`CFLAGS\*(C'\fR variable of the
applications \f(CW\*(C`Makefile\*(C'\fR.
.Ip "\fB\*(--ldflags\fR" 4
.IX Item "ldflags"
Prints the linker flags (\f(CW\*(C`\-L\*(C'\fR) which are needed to link the application with
the \fIl2\fR\|(3) library. The output is usually added to the \f(CW\*(C`LDFLAGS\*(C'\fR variable of
the applications \f(CW\*(C`Makefile\*(C'\fR.
.Ip "\fB\*(--libs\fR" 4
.IX Item "libs"
Prints the library flags (\f(CW\*(C`\-l\*(C'\fR) which are needed to link the application with
the \fIl2\fR\|(3) library. The output is usually added to the \f(CW\*(C`LIBS\*(C'\fR variable of the
applications \f(CW\*(C`Makefile\*(C'\fR.
