+.SH NAME
+libcurl\-easy \- easy interface overview
+.SH DESCRIPTION
+When using libcurl\(aqs "easy" interface you init your session and get a handle
+(often referred to as an "easy handle"), which you use as input to the easy
+interface functions you use. Use \fIcurl_easy_init(3)\fP to get the handle.
+
+You continue by setting all the options you want in the upcoming transfer, the
+most important among them is the URL itself (you cannot transfer anything
+without a specified URL). You might want to set some callbacks as well that
+are called from the library when data is available etc. For example
+\fICURLOPT_WRITEFUNCTION(3)\fP. \fIcurl_easy_setopt(3)\fP is used for all this.
+
+\fICURLOPT_URL(3)\fP is the only option you really must set, as otherwise there can
+be no transfer. Another commonly used option is \fICURLOPT_VERBOSE(3)\fP that helps
+you see what libcurl is doing under the hood, which is useful when debugging
+for example. The \fIcurl_easy_setopt(3)\fP man page has a full index of the over 300
+available options.
+
+If you at any point would like to blank all previously set options for a
+single easy handle, you can call \fIcurl_easy_reset(3)\fP and you can also make a
+clone of an easy handle (with all its set options) using
+\fIcurl_easy_duphandle(3)\fP.
+
+When all is setup, you tell libcurl to perform the transfer using
+\fIcurl_easy_perform(3)\fP. It performs the entire transfer operation and does not
+return until it is done (successfully or not).
+
+After the transfer has been made, you can set new options and make another
+transfer, or if you are done, cleanup the session by calling
+\fIcurl_easy_cleanup(3)\fP. If you want persistent connections, you do not cleanup
+immediately, but instead run ahead and perform other transfers using the same
+easy handle.
