+.SH NAME
+pcap-config \- write libpcap compiler and linker flags to standard output
+.SH SYNOPSIS
+.na
+.B pcap-config
+[
+.B \-\-static
+]
+[
+.B \-\-cflags | \-\-libs | \-\-additional-libs
+]
+.ad
+.SH DESCRIPTION
+.LP
+When run with the
+.B \-\-cflags
+option,
+.I pcap-config
+writes to the standard output the
+.B \-I
+compiler flags required to include libpcap's header files.
+When run with the
+.B \-\-libs
+option,
+.I pcap-config
+writes to the standard output the
+.B \-L
+and
+.B \-l
+linker flags required to link with libpcap, including
+.B \-l
+flags for libraries required by libpcap.
+When run with the
+.B \-\-additional-libs
+option,
+.I pcap-config
+writes to the standard output the
+.B \-L
+and
+.B \-l
+flags for libraries required by libpcap, but not the
+.B \-lpcap
+flag to link with libpcap itself.
+.LP
+By default, it writes flags appropriate for compiling with a
+dynamically-linked version of libpcap; the
+.B \-\-static
+flag causes it to write flags appropriate for compiling with a
+statically-linked version of libpcap.
