+.SH NAME
+libcurl-share \- how to use the share interface
+.SH DESCRIPTION
+This is an overview on how to use the libcurl share interface in your C
+programs. There are specific man pages for each function mentioned in
+here.
+
+All functions in the share interface are prefixed with curl_share.
+
+.SH "OBJECTIVES"
+The share interface was added to enable sharing of data between curl
+\&"handles".
+.SH "ONE SET OF DATA - MANY TRANSFERS"
+You can have multiple easy handles share data between them. Have them update
+and use the \fBsame\fP cookie database or DNS cache! This way, each single
+transfer will take advantage from data updates made by the other transfer(s).
+.SH "SHARE OBJECT"
+You create a shared object with \fIcurl_share_init()\fP. It returns a handle
+for a newly created one.
+
+You tell the shared object what data you want it to share by using
+\fIcurl_share_setopt()\fP. Currently you can only share DNS and/or COOKIE
+data.
+
+Since you can use this share from multiple threads, and libcurl has no
+internal thread synchronization, you must provide mutex callbacks if you're
+using this multi-threaded. You set lock and unlock functions with
+\fIcurl_share_setopt()\fP too.
+
+Then, you make an easy handle to use this share, you set the CURLOPT_SHARE
+option with \fIcurl_easy_setopt\fP, and pass in share handle. You can make any
+number of easy handles share the same share handle.
+
+To make an easy handle stop using that particular share, you set CURLOPT_SHARE
+to NULL for that easy handle. To make a handle stop sharing a particular data,
+you can CURLSHOPT_UNSHARE it.
+
+When you're done using the share, make sure that no easy handle is still using
+it, and call \fIcurl_share_cleanup()\fP on the handle.
