Reverting a concrete revision

[rolo2002]

        Hi All,

        Using i.e "cvs update -j <revision 1.6> -j <revision 1.3> file.c", we 
discard changes from 1.6 to 1.3. Then, commiting, we get revision 1.7 that is 
exactly the same as 1.3. Now, suppose I want to generate a new revision of 
"file.c" but containing code from 1.1 to 1.3 + 1.5 and 1.6 revision, because I 
realise that I don not want the changes made on revision 1.4 but still want all 
the changes made in 1.5 and 1.6. Doing the previous update, I lost 1.4 changes 
but also 1.5 and 1.6. So the idea is revert ONLY the changes that were made on 
1.4. If the changes of 1.5 and 1.6 are small (or changes of 1.) it can be do it 
manually but this is not my case.

        Is there any way to do this in CVS?

        Thanks in advance
