# NAME
#         colf — compile Colfer schemas
#
# SYNOPSIS
#         colf [ options ] language [ file ... ]
#
# DESCRIPTION
#         Generates source code for a language. The options are: C, Go,
#         Java and JavaScript.
#         The file operands specify the input. Directories are scanned for
#         files with the colf extension. If file is absent, colf includes
#         the working directory.
#         A package can have multiple schema files.
#
# OPTIONS
#   -b directory
#         Use a specific destination base directory. (default ".")
#   -f    Normalizes schemas on the fly.
#   -l expression
#         Sets the default upper limit for the number of elements in a
#         list. The expression is applied to the target language under the
#         name ColferListMax. (default "64 * 1024")
#   -p prefix
#         Adds a package prefix. Use slash as a separator when nesting.
#   -s expression
#         Sets the default upper limit for serial byte sizes. The
#         expression is applied to the target language under the name
#         ColferSizeMax. (default "16 * 1024 * 1024")
#   -v    Enables verbose reporting to the standard error.
#
# EXIT STATUS
#         The command exits 0 on succes, 1 on compilation failure and 2
#         when invoked without arguments.
#
# EXAMPLES
#         Compile ./api/*.colf into ./src/ as Java:
#
#                 colf -p com/example -b src java api
#
#         Compile ./io.colf with compact limits as C:
#
#                 colf -s 2048 -l 96 c io.colf
