CLOC 1.51

It is written entirely in Perl with no dependencies outside the standard distribution of Perl v5.6 and higher (code from some external modules is embedded within cloc) and so is quite portable. cloc is known to run on many flavors of Linux, Mac OS X, AIX, Solaris, IRIX, z/OS, and Windows. (To run the Perl source version of cloc on Windows one needs ActiveState Perl 5.6.1 or higher, or Cygwin installed. Alternatively one can use the Windows binary of cloc generated with perl2exe to run on Windows computers that have neither Perl nor Cygwin.)

cloc has many features that make it easy to use, thorough, extensible, and portable:

1. Exists as a single, self-contained file that requires minimal installation effort---just download the file and run it.
2. Can read language comment definitions from a file and thus potentially work with computer languages that do not yet exist.
3. Allows results from multiple runs to be summed together by language and by project.
4. Can produce results in a variety of formats: plain text, SQL, XML, YAML, comma separated values.
5. Can count code within compressed archives (tar balls, Zip files, Java .ear files).
6. Has numerous troubleshooting options.
7. Handles file and directory names with spaces and other unusual characters.
8. Has no dependencies outside the standard Perl distribution.
9. Runs on Linux, FreeBSD, NetBSD, Mac OS X, AIX, HP-UX, Solaris, IRIX, and z/OS systems that have Perl 5.6 or higher. The source version runs on Windows with either ActiveState Perl or cygwin. Alternatively on Windows one can run the Windows binary which has no dependencies.
