 Substitution takes place on every commit and update of the working
 repository.
 
+Caveat: "hg import" might fail if the patches were exported from a

 Configuration is done in the [keyword] and [keywordmaps] sections of
 hgrc files.
 
 Example:
+     [keyword]
      # filename patterns for expansion are configured in this section
      # files matching patterns with value 'ignore' are ignored
-     [keyword]
-     **.py =

+     **.py =          ## expand keywords in all python files
+     x* = ignore      ## but ignore files matching "x*"
      ...
-     # in case you prefer your own keyword maps over the cvs-like defaults:
      [keywordmaps]
+     # custom hg template maps _replace_ the CVS-like default ones
      HGdate = {date|rfc822date}
      lastlog = {desc} ## same as {desc|firstline} in this context
