xxccrruunn
     xxccrruunn - run or locate development tools

SYNOPSIS
     xxccrruunn [-ssddkk SDK] -ffiinndd 

     xxccrruunn [-ssddkk SDK] [-lloogg]  []

     <> []

DESCRIPTION
     xxccrruunn provides a means locate or invoke coexistence- and platform-aware
     developer tools from the command-line, without requiring users to modify
     makefiles or otherwise take laborious or inconvenient measures to adopt
     Xcode's multiple tool chains.

     xcode-select is used to specify which installation of Xcode is used, and
     may be overridden by the DEVELOPERDIR environment variable.

     The SDK defaults to the current OS SDK, and can be specified by SDKROOT
     environment variable or the -sdk flag (which takes precedences over SDK-
     ROOT).

UUSSAAGGEE
     The first usage returns the full path to the found toolname.

     The second usage executes toolname with the given toolarguments.

     The last syntax is when xxccrruunn replaces any of the standard UNIX developer
     tools (typically in /usr/bin).  In this case, xxccrruunn will use its tool
     name to locate the corresponding tool within evaluated DEVELOPERDIR and
     SDK.

     If the tool is not named xxccrruunn , toolarguments are not parsed by xxccrruunn.

OOPPTTIIOONNSS
     -vveerrbboossee
           display information about how the redirected path is constructed.

     -nnoo-ccaacchhee
           don't consult the cache when looking up values.  In effect, causes
           the cache to be refreshed.

     -ssddkk SDK
           specifies which SDK to use.  Overrides any SDKROOT set in the envi-
           ronment.

     -lloogg  print the full command line that is invoked.

     -ffiinndd
           print the full path to the tool.

ENVIRONMENT
     DEVELOPERDIR - specifies the search path for locating the current
     developer tools (overrides xcode-select default).

     SDKROOT - specifies the SDK to use; overriden by the command line -sdk
     flag.

     xcrunlog - same as specifying -log

     xcrunnocache - same as specifying -no-cache

     xcrunverbose - same as specifying -verbose


DIAGNOSTICS
     When xxccrruunn is invoked with the name xxccrruunn , the flags -log and -verbose
     are useful debugging aids.  The flag -no-cache can be used to bypass
     cache lookup.

     When xxccrruunn as taken the place of another tool, the arguments are those of
     the tool replaced, and the various xxccrruunn flags can't be used.  In this
     case, use the specific environment variables instead.
