NAME Programs

SYSNOPSIS

use Bio::EnsEMBL::Analysis::Programs qw( efetch getz est2genome 
                 /usr/local/bin/this_one
                 ~me/some/path/my_prog
                 ~/../jane/bin/her_prog );

# Can also do at run time
Bio::EnsEMBL::Analysis::Programs->import( $someProg );

$path_to_prog = $Bio::EnsEMBL::Analysis::Programs::Program_Paths{ $prog };

DESCRIPTION

Programs is used to check at compile time for the presence of executables which will be called from your script. Arguments passed via the use statement can be just the program name, or an absolute or relative path to the program. Tildes are expanded correctly (not using "glob"). Failure to find any one program is fatal, and a list of all failures is printed, along with the host''s name.

If you want to check for a program during run time, the import funtion can be called directly, as shown above.

The paths to each program found are stored in the %Program_Paths hash, which is keyed on the original arguments passed.

BUGS

If the executable is in the root directory, then it''s found path will appear as "//prog" in %Program_Paths, not "/prog".
