Currently, a number of commands and help topics mention the user hgrc
file in different ways. Among these are following:
1. .hgrc - "please specify your commit editor/username in your .hgrc
file", bookmarks, color, hgk, pager, hg help environment
2. $HOME/.hgrc - hg help paths, hgrc(5), hg(1)
3. ~/.hgrc - hgrc(5)
In addition to being inconsistent, none of these make sense on
Windows. This patch replaces the above with a more general term of
"[your] configuration file".
Remove the `install_package_data' subclass of `install_data' and use
the `package_data' functionality provided by distutils instead. As
package data must be located within the package directory, the data
files are now generated in the build directory.
To simplify the functionality of this change, the top-level `doc' and
`templates' directories have been moved into the `mercurial' package
directory.
