How can I identify if a given file is handled by git/cvs/svn/hg ?
If I know that, how can I get the version number of the file ?

///

(Given file in dir, which is the current dir)
Identification

rcs
  does file,v or RCS/file,v exist

cvs
  does dir CVS exist

git
  does dir .git (or ../.git etc.) exist and contain the dirs
  objects and refs

svn
  dir contains dir .svn

hg
  ???

///

  version string

  rcs
$ rcs -i zz
RCS file: zz,v
enter description, terminated with single '.' or end of file:
NOTE: This is NOT the log message!
>> test
>> .
done
$ ci zz
zz,v  <--  zz
initial revision: 1.1
done
$ rlog zz | grep ^revision
revision 1.1
$

  cvs
$ cd /Net/cvs/cvs.gedasymbols.org/www/user/ales_hvezda/symbols/
$ grep 16c450n-1.sym CVS/Entries | ( IFS=/ read a b c d; echo $c )
1.1
$
