Context grep (cgrep) from University of Waterloo. A tech report explaining
cgrep is accessible from:

http://plg.uwaterloo.ca/~ftp/mt/cgrep/

Structure grep (sgrep) can be found at:

http://www.cs.helsinki.fi/u/jjaakkol/sgrep.html

I have compiled a set of links to grep variances at:

http://flame.cs.dal.ca/~taa/greps.html

And a survey-style write up of most of them can be found at:

http://flame.cs.dal.ca/~taa/papers/abou-assaleh_csci6306a.pdf

BTW, the GNU grep TODO file states:

"Take a look at cgrep (Context grep) seems like nice work.
Take a look at sgrep (Struct grep).
Take a look at agrep (Approximate grep), from glimpse.
Can we merge ?"

The work I did with Wei Ai as an academic project of porting some features
from cgrep to GNU grep are described in "Enhancing GNU grep" available at:
