dnl  Rules for library version information:

dnl
 | 
						|
dnl   1. Start with version information of `0:0:0' for each libtool library.
 | 
						|
dnl   2. Update the version information only immediately before a public release of
 | 
						|
dnl      your software. More frequent updates are unnecessary, and only guarantee
 | 
						|
dnl      that the current interface number gets larger faster.
 | 
						|
dnl   3. If the library source code has changed at all since the last update, then
 | 
						|
dnl      increment revision (`c:r:a' becomes `c:r+1:a').
 | 
						|
dnl   4. If any interfaces have been added, removed, or changed since the last update,
 | 
						|
dnl      increment current, and set revision to 0.
 | 
						|
dnl   5. If any interfaces have been added since the last public release, then increment
 | 
						|
dnl      age.
 | 
						|
dnl   6. If any interfaces have been removed since the last public release, then set age
