+-
+-Defaults for the options are specified in brackets.
+-
+-Configuration:
+- -h, --help display this help and exit
+- --help=short display options specific to this package
+- --help=recursive display the short help of all the included packages
+- -V, --version display version information and exit
+- -q, --quiet, --silent do not print \`checking ...' messages
+- --cache-file=FILE cache test results in FILE [disabled]
+- -C, --config-cache alias for \`--cache-file=config.cache'
+- -n, --no-create do not create output files
+- --srcdir=DIR find the sources in DIR [configure dir or \`..']
+-
+-Installation directories:
+- --prefix=PREFIX install architecture-independent files in PREFIX
+- [$ac_default_prefix]

+- [PREFIX]

+-an installation prefix other than \`$ac_default_prefix' using \`--prefix',
+-for instance \`--prefix=\$HOME'.
+-
+-For better control, use the options below.

+-Fine tuning of the installation directories:

+Subject: [PATCH 3/6] libcoap: add new buildsystem
+
+This patch adds support for autotools buildsystem.
+
+The configure arguments can be:
+
+ --enable-debug
+ --disable-async
+ --disable-block
+ --disable-observe
+ --disable-query-filter
+
+the same like the real libcoap implementation.
+
+In addition I added a:
+
+ --with-max-pdu-size=COAP_MAX_PDU_SIZE
+
+to replace the COAP_MAX_PDU_SIZE define with a given number.

+Subject: [PATCH 4/6] libcoap: remove include of config.h
+
+We can't include "config.h" anymore because other software which
+use autotools with libcoap define the same defines into the his
+"config.h".
