This bundle adds LDIF support to TextMate.
For more complete support, you may want to add something like this to the CFBundleDocumentTypes section in TextMate.app/Contents/Info.plist:
{ CFBundleTypeName = "LDAP Data Interchange Format";
CFBundleTypeExtensions = (ldif);
CFBundleTypeIconFile = TMDocument;
},
You should make a backup copy of TextMate before you mess around inside it.
