Mercurial 中是否存在与 NIX 目录或文件的软链接或硬链接等价的东西。
基本上，文件（或目录）链接到“其他地方”的文件并遵循该位置的版本（与我认为必须合并的常规分支不同）

存储库内部的 Mercurial 版本软链接非常棒。它会检测它们、记录它们并为您创建它们。是否有您正在寻找的特定用例？与到达存储库外部的链接最接近的是子存储库，它是指向另一个存储库的特定版本的指针。
符号链接工作

*nix 上的路径审计
在 *nix 系统上，hgMercurial审核符号链接（“符号链接”）以确保引用路径的安全性。例如，绝对路径和空路径被认为是不安全的，因此不会添加到存储库中。
Mercurial 开发人员尚未记录此功能。但是，源代码包含一条注释，解释有点模糊：
class pathauditor(object):
'''ensure that a filesystem path contains no banned components.
the following properties of a path are checked:
- ends with a directory separator
- under top-level .hg
- starts at the root of a windows drive
- contains ".."
- traverses a symlink (e.g. a/symlink_here/b)
- inside a nested repository (a callback can be used to approve
some nested repositories, e.g., subrepositories)
'''
在 Windows 上，由于各种原因不支持符号链接，请参阅：
