55 # From the libtool info file, with comments:
57 # | 1. Start with version information of `0:0:0' for each libtool library.
59 # | 2. Update the version information only immediately before a public
60 # | release of your software. More frequent updates are unnecessary,
61 # | and only guarantee that the current interface number gets larger
64 # | 3. If the library source code has changed at all since the last
65 # | update, then increment REVISION (`C:R:A' becomes `C:r+1:A').
67 # [So it seems like we should always update the middle 'R' field
70 # | 4. If any interfaces have been added, removed, or changed since the
71 # | last update, increment CURRENT, and set REVISION to 0.
73 # | 5. If any interfaces have been added since the last public release,
74 # | then increment AGE.
76 # [These two rules seem to mean that if any change is made to the
77 # generator, we should increment C and A, and set R to 0, so:
80 # | 6. If any interfaces have been removed since the last public release,
81 # | then set AGE to 0.
83 # [Our ABI guarantee means we won't remove interfaces except in
84 # very exceptional circumstances.]
86 # The maximum proc number (see guestfs_protocol.x:guestfs_procedure) is
87 # a mostly accurate stand-in for C & A in rules 5 & 6, so we use that. It
88 # is always incremented when we add a new appliance interface, and easy to
91 # The middle number is hard to increment-and-reset as described in rules
92 # 4 & 5, so for the moment it is always set to 0.
94 # Note that this scheme means the real library version will always be
95 # 'libguestfs.so.0.$(MAX_PROC_NR).0'.
