+libcurl-symbols \- libcurl symbol version information
+.SH "libcurl symbols"
+This man page details version information for public symbols provided in the
+libcurl header files. This lists the first version in which the symbol was
+introduced and for some symbols two additional information pieces:
+
+The first version in which the symbol is marked "deprecated" - meaning that
+since that version no new code should be written to use the symbol as it is
+marked for getting removed in a future.
+
+The last version that featured the specific symbol. Using the symbol in source
+code will make it no longer compile error-free after that specified version.
+
+This man page is automatically generated from the symbols-in-versions file.
