File::SearchPath - Search for a file in a PATH-like environment variable This module can be used to search for files (which do not have to be executable) in a set of directories specified in a PATH-like environment variable such as $PATH, $LD_LIBRARY_PATH (or any environment variable). INSTALLATION % perl Makefile.PL % make % make test % make install REQUIREMENTS Should work on any perl. Can use the Env::Path module if it is present, else colon-separated path variables are assumed.
