The future-1.2.1 branch has multiple heads

#We do this so that people who launch Xcode from the UI will be able to run
#hg.  If we come across any other paths here where people would install
#hg by default, we should add them here.
PATH="$PATH:/opt/local/bin:/usr/local/bin:/sw/bin"

#this is done because the mercurial source install seems to put it in this location
export PYTHONPATH="$PYTHONPATH:/usr/local/lib/python2.6/site-packages"

#this is done because Xcode won't actually run the script if the output file already exists, which is bad
HEADERPATH="$TARGET_BUILD_DIR/include/hgRevision.h"

#hg parent will present two revisions if the user has a pending merge.
#The user probably shouldn't be building in such a circumstance, but,
#nonetheless, we should handle it sanely. We do this by only showing the
#first parent.
REVISION=`hg parent --template="{rev}\n" | head -n1`

Tip: Filter by directory path e.g. /media app.js to search for public/media/app.js.
Tip: Use camelCasing e.g. ProjME to search for ProjectModifiedEvent.java.
Tip: Filter by extension type e.g. /repo .js to search for all .js files in the /repo directory.
Tip: Separate your search with spaces e.g. /ssh pom.xml to search for src/ssh/pom.xml.
Tip: Use ↑ and ↓ arrow keys to navigate and return to view the file.
Tip: You can also navigate files with Ctrl+j (next) and Ctrl+k (previous) and view the file with Ctrl+o.
Tip: You can also navigate files with Alt+j (next) and Alt+k (previous) and view the file with Alt+o.
