Modified debug output to more closely track interactions with the underlying
cvmfs library, rather than calls to the parrot module.
When checking for an intermediate link after a failed stat,
only continue down the tree when the path element exists.
Look for package variants based on redhatX.  Necessary for cvmfs,
where the redhat5 build is not compatible with the redhat6 build.
Attempt to open a directory should return EISDIR.
Whitespace to force build against latest cvmfs.
Fixed stray dash.
Removed mention of hdfs from configure.afs
Parrot supports HDFS internally and does not have a compile-time dependency.
Parrot-cvmfs: stat should follow symbolic links, lstat should not.
Forcing rebuild of parrot after fixing bug in cvmfs:
https://github.com/cooperative-computing-lab/cvmfs/commit/772fd8da169a10ddb6b052584f4abf7938ff8f88
linkname is not used by dirent.
only remove absolute paths if able
more specific path for linker testing
When rewriting a name via the mount list, avoid putting in a double slash,
which upsets some remote services.
Added examples of using parrot to run cms and atlas simulation jobs.
Parrot should issue set/getpgid on behalf of the traced process.
This squelches a raft of warning messages that can come from an
interactive bash shell.
Minor documentation fix for WQ project names.
Create new "biotools" directory to hold WQ apps in bioinformatics and molecular
dynamics.

This also commits the first working version of WQ based maker to CCTools.
