1148
The branch is the branch you will merge from. By default, it will
1149
merge the latest revision. If you specify a revision, that
1150
revision will be merged. If you specify two revisions, the first
1151
will be used as a BASE, and the second one as OTHER. Revision
1152
numbers are always relative to the specified branch.
1153
1154
By default bzr will try to merge in all new work from the other
1155
branch, automatically determining an appropriate base. If this
1156
fails, you may need to give an explicit base.
1157
1158
Examples:
1159
1160
To merge the latest revision from bzr.dev
1161
bzr merge ../bzr.dev
1162
1163
To merge changes up to and including revision 82 from bzr.dev
1164
bzr merge -r 82 ../bzr.dev
1165
1166
To merge the changes introduced by 82, without previous changes:
1167
bzr merge -r 81..82 ../bzr.dev
1168
1169
merge refuses to run if there are any uncommitted changes, unless
