Path of a tag in the Subversion repository using a build name. The path is computed relatively to the root of the repository.
The {build} placeholder is used to define the location where
to replace the path fragment by the build name. An optional expression can follow
the build keyword: {build:expression}. In this case the build name
must match the expression, where * stands for any suite of characters.
For example: {build:2.7.*} will match build 2.7.0-15,
but not 2.8.0.
