+0.1.20 (2013-10-07) 
+    - socket close code fixed. Thanks to Martin J. Levy.
+
+0.1.19 (2013-05-09)
+    - CLANG compilation issues fixed.
+    - bgpq3.spec added. Thanks to Arnoud Vermeer.
+    
+0.1.18 (2013-01-08)
+    - JSON output format. Thanks to Job Snijders (Atrato Networks).
+
+0.1.17 (2012-10-25)
+    - route-sets handling in command-line added. Thanks to Alexandr Turovsky
+    for pointing out.
+    - bug in aggregation documentation fixed. Thanks to Nikolay Shopik.
+
+0.1.16 (2012-01-19)
+    - new option -m <len>: maximum length of accepted prefixes. 
+    Suggested by Eugene Demidov, used to discard 'too long prefixes'
+    (like /30-/32) even if they are registered in IRR. By default 
+    limit is not set and all prefixes accepted.
+    - documentation redesigned into text/markdown and text/html (manpage 
+    supported still).
+
+0.1.15 (2011-07-15)
+    - prefix-set's for Cisco IOS XR now supported too. 
+
+0.1.14 (2011-06-18)
+    - Fixed bug in sx_maxsockbuf in rare cases of OS maxsockbuf >2M. 
+    Thanks to Andreas Lundin.
+
+0.1.13 (2011-06-14)
+    - never publically released.
+
+0.1.12 (2010-10-08)
+    - Fixed bug preventing AS262144 (that's AS4.0 in asdot) to expand. 
+    Thanks to Sergey Matveychuk
+
+0.1.11 (2010-04-19)
+    - Fixed another bug in aggregation (-A) mode, thanks to Dmitry Tejblum.
+
+0.1.10 (2009-06-13)
+    - Fixed bug in aggregation (-A) mode, thanks to Sergey Gonchar. 
+
+0.1.9 (2009-03-27)
+    - RIPE changed ASN32 notation to asplain. And RADB does not support
+    asplain indexing (yet?).... Fixed. Thanks to Pavel Gluchouk. 
+
+0.1.8 (2008-12-25)
+    - new flag -D for Cisco asdot notation. Cisco behaviour is a bit
+    strange for me, but, well, that's their decision: 
+When the asdot format is enabled as the default, any regular expressions 
+to match 4-byte autonomous system numbers must be written using the asdot 
+format, or else the regular expression match will fail. 
+    (c) http://www.cisco.com/en/US/docs/ios/12_0s/release/ntes/120SNEWF.html
+        #wp3521658 (note the URL wrap). 
+
+0.1.7 (2008-12-19): 
+    - man page. Finally :) 
+    - option -h now means not help, but now it can be used to point to 
+    alternate IRRD host, like in old bgpq.
+
+0.1.6 (2008-08-08): 
+    - maxsockbuf call added, that can help with pipelining of really large
+    as-sets.
+    - new key -M <extra match condition> for juniper route-filters, f.e.: 
+    bgpq3 -JEM "protocol bgp;\n    community no-export" -l PolicyName/TermName 
+    will generate term with additional match conditions, like: 
+
+    policy-options {
+     policy-statement PolicyName {
+      term TermName {
+    replace:
+       from {
+        protocol bgp;
+        community no-export;
+        route-filter 10.0.0.0/24 exact;
+       }
+      }
+     }
+    }
+
+0.1.5 (2008-06-02): 
+    - route-set's expansion added. Fully functional for IPv4 prefixes, but
+    not for IPv6 - only those prefixes explicitely marked as 'member-of: RS..'
+    will be expanded. This is due to limitation in IRRd.
+    - extended access-lists (Cisco) and route-filters (Juniper) generation
+    is supported now with new -E key. For Cisco ipv6 access-lists is not
+    yet supported. 
+
+0.1.4 (2008-05-30): 
+    - bugfix for juniper as-path group generation. Thanks to Alexander Shikoff.
+
+0.1.3 (2008-05-20): 
+    - aggregation (-A) now supported for Cisco prefix-lists. 
+    - pipelining now can be enabled for RIPE-style queries too (ipv6). 
+    - more-specific routes (-R len) feature ported from bgpq
+    - pipelining now set by default. -T flag now disables pipelining.
+    - strlcpy.c imported into sources. Not found on Linux :) 
+
+0.1.2 (2008-05-19): 
+    - final support for asn32, now with correct syntax for Juniper. 
+    - experimental 'pipelining' mode (flag -T), much faster when 
+    working with big as-set's. 
+    - RIPE-style query (-i origin) now requests only route6 objects. 
+
+0.1.1 (2008-05-16): 
+    - initial support for asn32 added (flag -3). By default it's off, 
+    and when bgpq sees 32-bit asn in resolver queue, it either replaces
+    it with AS23456 (in as-path generation mode) or queries radb for
+    prefixes with that origin. 
+    Note: for now only JunOS 9.1 can handle asn32, not Cisco IOS..

+formats supported).
+.It Fl d
+enable some debugging output.
+.It Fl D
+use asdot notation for Cisco as-path access-lists.

+route-filters (Juniper).
+.It Fl f Ar number
+generate input as-path access-list.
+.It Fl G Ar number
+generate output as-path access-list.
+.It Fl h Ar host
+host running IRRD database (default: whois.radb.net).
+.It Fl J

+.It Fl j
+generate output in JSON format (default: Cisco).
+.It Fl m Ar len
+maximum prefix-length of accepted prefixes (default: 32 for IPv4 and 
+128 for IPv6).
+.It Fl M Ar match 
+extra match conditions for Juniper route-filters.

+.Pp
+For Cisco we can use aggregation (-A) flag to make this prefix-filter

+.RE

+- you see, prefixes 89.112.0.0/19 and 89.112.32.0/19 now aggregated
+into single entry 89.112.0.0/18 ge 19 le 19. 
+.Pp
+Well, for Juniper we can generate even more interesting policy-options,
+using -M <extra match conditions>, -R <len> and hierarchical names: 
+.nf
+.RS
+~>bgpq3 -AJEl eltel/specifics -R 32 -M "community blackhole" AS20597
+policy-options {
+ policy-statement eltel {
+  term specifics {

+   }
+  }
+ }
+}
+.RE
+.fi
+generated policy-option term now allows all specifics for eltel networks
+if they match with special community 'blackhole'.
+.Pp
+Of course, this version supports IPv6 (-6): 
+.nf
+.RS
+~>bgpq3 -6l as-retn-6 AS-RETN6
+no ipv6 prefix-list as-retn-6
+ipv6 prefix-list as-retn-6 permit 2001:7fb:fe00::/48
+ipv6 prefix-list as-retn-6 permit 2001:7fb:fe01::/48
+[....]
+.RE
+.fi
+and support for ASN 32 is also here
+.nf
+.RS
+~>bgpq3 -J3f 112 AS-SPACENET
+policy-options {
+replace:
+ as-path-group NN {
+  as-path a0 "^112(112)*$";
+  as-path a1 "^112(.)*(1898|5539|8495|8763|8878|12136|12931|15909)$";

+ }
+}
+.RE
+.fi
+see AS196611 in the end of the list ? That's AS3.3 in 'asplain' notation. 
+.Pp
+For non-ASN32 capable routers you should not use switch -3, 
+and the result will be next: 
+.nf
+.RS
+~>bgpq3 -f 112 AS-SPACENET
+no ip as-path access-list NN
+ip as-path access-list NN permit ^112(_112)*$

+ip as-path access-list NN permit ^112(_[0-9]+)*_(35052|41720|43628|44450)$
+.RE
+.fi
+.Pp
+AS196611 is no more in the list, however, AS23456 (transition AS)
+would be added to list if it were not present. 
+.Sh DIAGNOSTICS
+When everything is OK, 
+.Nm
+generates access-list to standard output and exits with status == 0. 
+In case of errors they are printed to stderr and program exits with 
+non-zero status.

+<h2>NAME</h2>
+
+<p><code>bgpq3</code> - bgp filtering automation for Cisco and Juniper routers</p>
+
+<h2>SYNOPSIS</h2>
+
+<pre><code>bgpq3 [-h host] [-S sources] [-EP] [-f asn | -G asn] [-36ADdJjX] [-R len] [-m max] OBJECTS [...]
+</code></pre>
+
+<h2>DESCRIPTION</h2>
+
+<p>The bgpq3 utility used to generate Cisco and Juniper prefix-lists,
+extended access-lists, policy-statement terms and as-path lists based on
+RADB data.</p>
+
+<p>The options are as follows:</p>
+
+<ul>
+<li><p>-3      </p>
+
+<blockquote>
+  <p>assume that your device is asn32-capable.</p>
+</blockquote></li>
+<li><p>-6      </p>
+
+<blockquote>
+  <p>generate IPv6 prefix/access-lists (IPv4 by default).</p>
+</blockquote></li>
+<li><p>-A      </p>
+
+<blockquote>
+  <p>try to aggregate generated filters as much as possible (not all
+  output formats supported).</p>
+</blockquote></li>
+<li><p>-d      </p>
+
+<blockquote>
+  <p>enable some debugging output.</p>
+</blockquote></li>
+<li><p>-D      </p>
+
+<blockquote>
+  <p>use asdot notation for Cisco as-path access-lists.</p>
+</blockquote></li>
+<li><p>-E      </p>
+
+<blockquote>
+  <p>generate extended access-list (Cisco) or policy-statement term using 
+  route-filters (Juniper).</p>
+</blockquote></li>
+<li><p>-f number</p>
+
+<blockquote>
+  <p>generate input as-path access-list.</p>
+</blockquote></li>
+<li><p>-G number</p>
+
+<blockquote>
+  <p>generate output as-path access-list.</p>
+</blockquote></li>
+<li><p>-h host</p>
+
+<blockquote>
+  <p>host running IRRD database (default: whois.radb.net).</p>
+</blockquote></li>
+<li><p>-J      </p>
+
+<blockquote>
+  <p>generate config for Juniper (default: Cisco).</p>
+</blockquote></li>
+<li><p>-j      </p>
+
+<blockquote>
+  <p>generate output in JSON format (default: Cisco).</p>
+</blockquote></li>
+<li><p>-m len  </p>
+
+<blockquote>
+  <p>maximum length of accepted prefixes (default: 32 for IPv4, 128 for IPv6).</p>
+</blockquote></li>
+<li><p>-M match </p>
+
+<blockquote>
+  <p>extra match conditions for Juniper route-filters.</p>
+</blockquote></li>
+<li><p>-l name </p>
+
+<blockquote>
+  <p>name of generated entry.</p>
+</blockquote></li>
+<li><p>-P      </p>
+
+<blockquote>
+  <p>generate prefix-list (default behaviour, flag added for backward 
+  compatibility only).</p>
+</blockquote></li>
+<li><p>-R len  </p>
+
+<blockquote>
+  <p>allow more-specific routes up to specified masklen too.
+  (Please, note: objects with prefix-length greater than specified length
+  will be always allowed.)</p>
+</blockquote></li>
+<li><p>-S sources </p>
+
+<blockquote>
+  <p>use specified sources only (default: RADB,RIPE,APNIC).</p>
+</blockquote></li>
+<li><p>-T      </p>
+
+<blockquote>
+  <p>disable pipelining.</p>
+</blockquote></li>
+<li><p>-X      </p>
+
+<blockquote>
+  <p>generate config for Cisco IOS XR devices (plain IOS by default).</p>
+</blockquote></li>
+</ul>
+
+<p><code>OBJECTS</code> means networks (in prefix format), autonomous systems and as-macros.</p>
+
+<h2>EXAMPLES</h2>
+
+<p>Generating named Juniper prefix-filter for <code>AS20597</code>:</p>
+
+<pre><code> user@host:~&gt;bgpq3 -Jl eltel AS20597
+ policy-options {
+ replace:
+  prefix-list eltel {
+     81.9.0.0/20;
+     81.9.32.0/20;
+     81.9.96.0/20;
+     81.222.128.0/20;
+     81.222.192.0/18;
+     85.249.8.0/21;
+     85.249.224.0/19;
+     89.112.0.0/19;
+     89.112.4.0/22;
+     89.112.32.0/19;
+     89.112.64.0/19;
+     217.170.64.0/20;
+     217.170.80.0/20;
+  }
+ }
+</code></pre>
+
+<p>For Cisco we can use aggregation (-A) flag to make this prefix-filter
+more compact:</p>
+
+<pre><code> user@host:~&gt;bgpq3 -Al eltel AS20597
+ no ip prefix-list eltel
+ ip prefix-list eltel permit 81.9.0.0/20
+ ip prefix-list eltel permit 81.9.32.0/20
+ ip prefix-list eltel permit 81.9.96.0/20
+ ip prefix-list eltel permit 81.222.128.0/20
+ ip prefix-list eltel permit 81.222.192.0/18
+ ip prefix-list eltel permit 85.249.8.0/21
+ ip prefix-list eltel permit 85.249.224.0/19
+ ip prefix-list eltel permit 89.112.0.0/18 ge 19 le 19
+ ip prefix-list eltel permit 89.112.4.0/22
+ ip prefix-list eltel permit 89.112.64.0/19
+ ip prefix-list eltel permit 217.170.64.0/19 ge 20 le 20
+</code></pre>
+
+<p>and, as you see, prefixes <code>89.112.0.0/19</code> and <code>89.112.32.0/19</code> now aggregated 
+into single entry </p>
+
+<pre><code>ip prefix-list eltel permit 89.112.0.0/18 ge 19 le 19.
+</code></pre>
+
+<p>Well, for Juniper we can generate even more interesting policy-statement,
+using <code>-M &lt;extra match conditions&gt;</code>, <code>-R &lt;len&gt;</code> and hierarchical names:</p>
+
+<pre><code> user@host:~&gt;bgpq3 -AJEl eltel/specifics -R 32 -M "community blackhole" AS20597
+ policy-options {
+  policy-statement eltel {
+   term specifics {
+ replace:
+    from {
+     community blackhole;
+     route-filter 81.9.0.0/20 upto /32;
+     route-filter 81.9.32.0/20 upto /32;
+     route-filter 81.9.96.0/20 upto /32;
+     route-filter 81.222.128.0/20 upto /32;
+     route-filter 81.222.192.0/18 upto /32;
+     route-filter 85.249.8.0/21 upto /32;
+     route-filter 85.249.224.0/19 upto /32;
+     route-filter 89.112.0.0/18 prefix-length-range /19-/32;
+     route-filter 89.112.64.0/19 upto /32;
+     route-filter 217.170.64.0/19 prefix-length-range /20-/32;
+    }
+   }
+  }
+ }
+</code></pre>
+
+<p>generated policy-option term now allows all more-specific routes 
+for eltel networks if they marked with community 'blackhole' (defined
+elsewhere in configuration).</p>
+
+<p>Of course, <code>bgpq3</code> supports IPv6 (-6):</p>
+
+<pre><code> user@host:~&gt;bgpq3 -6l as-retn-6 AS-RETN6
+ no ipv6 prefix-list as-retn-6
+ ipv6 prefix-list as-retn-6 permit 2001:7fb:fe00::/48
+ ipv6 prefix-list as-retn-6 permit 2001:7fb:fe01::/48
+ [....]
+</code></pre>
+
+<p>and ASN32</p>
+
+<pre><code> user@host:~&gt;bgpq3 -J3f 112 AS-SPACENET
+ policy-options {
+ replace:
+  as-path-group NN {
+   as-path a0 "^112(112)*$";
+   as-path a1 "^112(.)*(1898|5539|8495|8763|8878|12136|12931|15909)$";
+   as-path a2 "^112(.)*(21358|23456|23600|24151|25152|31529|34127|34906)$";
+   as-path a3 "^112(.)*(35052|41720|43628|44450|196611)$";
+  }
+ }
+</code></pre>
+
+<p>see <code>AS196611</code> in the end of the list ? That's <code>AS3.3</code> in 'asplain' notation.</p>
+
+<p>If your router does not support ASN32 (yet) you should not use switch -3, 
+and the result will be next:</p>
+
+<pre><code> user@host:~&gt;bgpq3 -f 112 AS-SPACENET

+NAME

+
+`bgpq3` - bgp filtering automation for Cisco and Juniper routers
+
+SYNOPSIS
+--------
+
+	bgpq3 [-h host] [-S sources] [-EP] [-f asn | -G asn] [-36ADdJjX] [-R len] [-m max] OBJECTS [...]
+
+DESCRIPTION
+-----------
+
+The bgpq3 utility used to generate Cisco and Juniper prefix-lists,
+extended access-lists, policy-statement terms and as-path lists based on
+RADB data.
+
+The options are as follows:
+
+-    -3      
+
+	> assume that your device is asn32-capable.
+
+-    -6      
+
+	> generate IPv6 prefix/access-lists (IPv4 by default).
+
+-    -A      
+
+	> try to aggregate generated filters as much as possible (not all
+    output formats supported).
+
+-    -d      
+
+	> enable some debugging output.
+
+-    -D      
+
+	> use asdot notation for Cisco as-path access-lists.
+
+-    -E      
+
+	> generate extended access-list (Cisco) or policy-statement term using 
+	route-filters (Juniper).
+
+-    -f number
+
+	> generate input as-path access-list.
+
+-    -G number
+
+	> generate output as-path access-list.
+
+-    -h host
+
+	> host running IRRD database (default: whois.radb.net).
+
+-    -J      
+
+	> generate config for Juniper (default: Cisco).
+
+-    -j      
+
+	> generate output in JSON format (default: Cisco).
+
+-    -m len  
+
+	> maximum length of accepted prefixes (default: 32 for IPv4, 128 for IPv6).
+
+-    -M match 
+
+	> extra match conditions for Juniper route-filters.
+
+-    -l name 
+
+	> name of generated entry.
+
+-    -P      
+
+	> generate prefix-list (default behaviour, flag added for backward 
+	compatibility only).
+
+-    -R len  
+
+	> allow more-specific routes up to specified masklen too.
+	(Please, note: objects with prefix-length greater than specified length
+	will be always allowed.)
+
+-    -S sources 
+
+	> use specified sources only (default: RADB,RIPE,APNIC).
+
+-    -T      
+
+	> disable pipelining.
+
+-    -X      
+
+	> generate config for Cisco IOS XR devices (plain IOS by default).
+
+`OBJECTS` means networks (in prefix format), autonomous systems and as-macros.
+
+EXAMPLES
+--------
+
+Generating named Juniper prefix-filter for `AS20597`:
+
+     user@host:~>bgpq3 -Jl eltel AS20597
+     policy-options {
+     replace:
+      prefix-list eltel {
+         81.9.0.0/20;
+         81.9.32.0/20;
+         81.9.96.0/20;
+         81.222.128.0/20;
+         81.222.192.0/18;
+         85.249.8.0/21;
+         85.249.224.0/19;
+         89.112.0.0/19;
+         89.112.4.0/22;
+         89.112.32.0/19;
+         89.112.64.0/19;
+         217.170.64.0/20;
+         217.170.80.0/20;
+      }
+     }
+
+For Cisco we can use aggregation (-A) flag to make this prefix-filter
+more compact:
+
+     user@host:~>bgpq3 -Al eltel AS20597
+     no ip prefix-list eltel
+     ip prefix-list eltel permit 81.9.0.0/20
+     ip prefix-list eltel permit 81.9.32.0/20
+     ip prefix-list eltel permit 81.9.96.0/20
+     ip prefix-list eltel permit 81.222.128.0/20
+     ip prefix-list eltel permit 81.222.192.0/18
+     ip prefix-list eltel permit 85.249.8.0/21
+     ip prefix-list eltel permit 85.249.224.0/19
+     ip prefix-list eltel permit 89.112.0.0/18 ge 19 le 19
+     ip prefix-list eltel permit 89.112.4.0/22
+     ip prefix-list eltel permit 89.112.64.0/19
+     ip prefix-list eltel permit 217.170.64.0/19 ge 20 le 20
+
+and, as you see, prefixes `89.112.0.0/19` and `89.112.32.0/19` now aggregated 
+into single entry 
+
+	ip prefix-list eltel permit 89.112.0.0/18 ge 19 le 19.
+
+Well, for Juniper we can generate even more interesting policy-statement,
+using `-M <extra match conditions>`, `-R <len>` and hierarchical names:
+
+     user@host:~>bgpq3 -AJEl eltel/specifics -R 32 -M "community blackhole" AS20597
+     policy-options {
+      policy-statement eltel {
+       term specifics {
+     replace:
+        from {
+         community blackhole;
+         route-filter 81.9.0.0/20 upto /32;
+         route-filter 81.9.32.0/20 upto /32;
+         route-filter 81.9.96.0/20 upto /32;
+         route-filter 81.222.128.0/20 upto /32;
+         route-filter 81.222.192.0/18 upto /32;
+         route-filter 85.249.8.0/21 upto /32;
+         route-filter 85.249.224.0/19 upto /32;
+         route-filter 89.112.0.0/18 prefix-length-range /19-/32;
+         route-filter 89.112.64.0/19 upto /32;
+         route-filter 217.170.64.0/19 prefix-length-range /20-/32;
+        }
+       }
+      }
+     }
+
+generated policy-option term now allows all more-specific routes 
+for eltel networks if they marked with community 'blackhole' (defined
+elsewhere in configuration).
+
+Of course, `bgpq3` supports IPv6 (-6):
+
+     user@host:~>bgpq3 -6l as-retn-6 AS-RETN6
+     no ipv6 prefix-list as-retn-6
+     ipv6 prefix-list as-retn-6 permit 2001:7fb:fe00::/48
+     ipv6 prefix-list as-retn-6 permit 2001:7fb:fe01::/48
+     [....]
+
+and ASN32
+
+     user@host:~>bgpq3 -J3f 112 AS-SPACENET
+     policy-options {
+     replace:
+      as-path-group NN {
+       as-path a0 "^112(112)*$";
+       as-path a1 "^112(.)*(1898|5539|8495|8763|8878|12136|12931|15909)$";
+       as-path a2 "^112(.)*(21358|23456|23600|24151|25152|31529|34127|34906)$";
+       as-path a3 "^112(.)*(35052|41720|43628|44450|196611)$";
+      }
+     }
+
+see `AS196611` in the end of the list ? That's `AS3.3` in 'asplain' notation.
+
+If your router does not support ASN32 (yet) you should not use switch -3, 
+and the result will be next:
+
+     user@host:~>bgpq3 -f 112 AS-SPACENET
+     no ip as-path access-list NN
+     ip as-path access-list NN permit ^112( 112)*$
+     ip as-path access-list NN permit ^112( [0-9]+)* (1898|5539|8495|8763)$
+     ip as-path access-list NN permit ^112( [0-9]+)* (8878|12136|12931|15909)$
+     ip as-path access-list NN permit ^112( [0-9]+)* (21358|23456|23600|24151)$
+     ip as-path access-list NN permit ^112( [0-9]+)* (25152|31529|34127|34906)$
+     ip as-path access-list NN permit ^112( [0-9]+)* (35052|41720|43628|44450)$
+
+`AS196611` is no more in the list, however, `AS23456` (transition AS) would
+have been added to list if it were not present.
+
+DIAGNOSTICS
+-----------
+
+When everything is OK, `bgpq3` generates result to standard output and
+exits with status == 0.  In case of errors they are printed to stderr and
+program exits with non-zero status.
+
+NOTES ON ULTRA-LARGE PREFIX-LISTS
+---------------------------------
+
+When using `bgpq3` to expand extra-large AS-SETs, `bgpq3` may stuck
+due to lacking tcp buffer size. To avoid this, tune your OS. 
+FreeBSD can be tuned in the following way:
+
+    sysctl -w net.inet.tcp.sendbuf_max=16777216
+
+Please note that generated prefix-lists may not fit your router's
+limitations. For example, JunOS supports only 85,325 prefixes in 
+each prefix-list [4](http://www.juniper.net/techpubs/en_US/junos11.4/topics/reference/configuration-statement/prefix-list-edit-policy-options.html).

+\`configure' configures bgpq3 0.1.20 to adapt to many kinds of systems.
+
+Usage: $0 [OPTION]... [VAR=VALUE]...
+
+To assign environment variables (e.g., CC, CFLAGS...), specify them as
+VAR=VALUE.  See below for descriptions of some of the useful variables.
+
+Defaults for the options are specified in brackets.
+
+Configuration:
+  -h, --help              display this help and exit
+      --help=short        display options specific to this package
+      --help=recursive    display the short help of all the included packages
+  -V, --version           display version information and exit
+  -q, --quiet, --silent   do not print \`checking ...' messages
+      --cache-file=FILE   cache test results in FILE [disabled]
+  -C, --config-cache      alias for \`--cache-file=config.cache'
+  -n, --no-create         do not create output files
+      --srcdir=DIR        find the sources in DIR [configure dir or \`..']
+
+Installation directories:
+  --prefix=PREFIX         install architecture-independent files in PREFIX
+                          [$ac_default_prefix]
+  --exec-prefix=EPREFIX   install architecture-dependent files in EPREFIX
+                          [PREFIX]
+
+By default, \`make install' will install all the files in
+\`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc.  You can specify
+an installation prefix other than \`$ac_default_prefix' using \`--prefix',
+for instance \`--prefix=\$HOME'.
+
+For better control, use the options below.
