+# This script triggers a Travis CI build on trpl-ja-pdf to generates
+# PDF files of TRPL. It does so by sending a request to Travis's API
+# server.

+# This script referes to the following mandatory and optional
+# environment variables:
+#
+# - TRPL_JA_PDF_TRAVIS_AUTH_TOKEN (Mandatory):
+#     The auth token required by Travis CI web API. Since this
+#     variable carries a sensitive data, it should not be defined in
+#     circle.yml. Instead, it should be defined at Circle CI's web
+#     console at:
+#     https://circleci.com/gh/rust-lang-ja/the-rust-programming-language-ja/edit#env-vars
+#
+#     To obtain a Travis auth token, follow the instructions on:
+#     https://docs.travis-ci.com/user/triggering-builds/
+#
+# - TRPL_JA_PDF_GITHUB_ORG (Optional):
+#     The GitHub organization or user name of trpl-ja-pdf, default to
+#    `rust-lanu-ja`. To override it, define this variable at
+#    CirildCI's web console or in circle.yml.
+#
+# - TRPL_JA_PDF_GITHUB_REPO (Optional):
+#     The GitHub repository name of trpl-ja-pdf, default to
+#     `trpl-ja-pdf`. To override it, define this variable at
+#     CircleCI's web console or in circle.yml.
+#
+# - TRPL_JA_PDF_GITHUB_BRANCH (Optional):
+#     The GitHub branch of trpl-ja-pdf, default to `master`. To
+#     override it, define this variable at CircleCI's web console or
+#     in circle.yml.
